John has an account balance of $20. He receives his weekly paycheck
for work at his part-time job in the amount of $110. He can't find
a bike he wants, so he buys some comic books for $40. Then John
finds his dream bike priced as shown. If he buys the bike now, what
will his account balance be?

Answers

Step-by-step explanation:

Accounts balance=$20

Part time job salary=$110

Total balance

\begin{gathered}\\ \sf\longmapsto 110+20=130\$\end{gathered}

⟼110+20=130$

Now

Price of comics=$40

Price left for bike

\begin{gathered}\\ \sf\longmapsto 130-40=90\$\end{gathered}

⟼130−40=90$

After buying the dream bike, John's account balance will be -$110.

Let's calculate John's account balance after each transaction step by step:

1. Initial balance: $20

2. Weekly paycheck: +$110

  Account balance = $20 + $110 = $130

3. Buys comic books: -$40

  Account balance = $130 - $40 = $90

4. Buys dream bike: -$200

  Account balance = $90 - $200 = -$110

After buying the dream bike, John's account balance will be -$110. This means he will have a negative balance of $110, indicating that he owes the bank or whoever manages the account. It's important to be cautious with negative balances as they can result in overdraft fees or other penalties depending on the account type and the bank's policies.

Please help I don’t know what to do

Answers

Answer:

A is the answer

Answer:

the first one is the answer y = (x-2)^2 + 1

Step-by-step explanation:

The vertex form of a quadratic function is y = a(x – h)^2 + k, where a, h, and k are constants.  h and k are vertex.

vertex is (2,1) which is (h,k)

passes through (0,5)

Equation is  y = a( x - 2)^2 + 1 . now substituting (0,5) in for x and f(x),

5 = a ( 0 - 2) ^2 + 1 and solve for a.....

5 = 4a + 1

5-1 = 4a

4a = 4..........  a = 1

equation becomes y = 1(x-2)^2 + 1 or y= (x-2)^2 + 1

Find the perimeter of a rectangle with a length of 6x+3 and a width of -2x-5.

Answers

The simple way of calculating a perimeter is to add all of the sides.
For a rectangle this would equal 2 x length + 2 x width
P = 2(6x + 3) + 2(-2x - 5)
= 12x + 6 - 4x - 10
= 8x - 4

At a higher level both the length and width must be greater than zero (= zero is a trivial rectangle)
6x + 3 > 0
6x > -3
x > -0.5

-2x - 5 > 0
2x + 5 < 0 (multiplying by -1 reverses the inequality)
2x < -5
x < -2.5

This rectangle cannot exist as x cannot be < -2.5 and > -0.5 at the same time!

L=6x+3

B=-2x-5

A machine costing $56,745 with a 7-year life and $51,208 depreciable cost was purchased January 1. Compute the yearly depreciation expense using straight-line depreciation. Round your answer to the nearest whole dollar.
How much is per year?

Answers

Answer:

$7315

Step-by-step explanation:

To find the depreciation expense, we use this formula:

Depreciable cost ÷ useful life time

Depreciated cost = $51,208

Life time = 7 years

51,208 ÷ 7 = 7315.42857

This means that $51,208 were lost over the 7 years, meaning $7315 were lost every year.

19. Rashmika bought a second hand T.V. for Rs. 6,000 and she spent Rs. 1500 on its repair. She sold it for Rs. 5,500. Find her profit or loss.​

Answers

Cost of TV= Rs. 6000

Money spent on repair= Rs. 1500

So, money left after repair= 6000-1500= Rs. 4500

She sold it for Rs. 5,500

Therefore, Profit= 5500-4500= Rs. 1000

So profit= Rs. 1000

Answer:

2,000 loss

Step-by-step explanation:

Total Revenue - Total Expenses = Profit

Total expenses = 6,000(Original cost) + 1500(repairs) = 7,500

Total revenue =  selling price = 5,500

Therefore the Profit or Loss(negative number) =

        5,500 - 7,500 = -2000 or 2,000 loss

2. A laptop usually sells for £1320 (including VAT). A store is advertising a discount of 15%
if it is purchased on a Sunday and a further 10% student discount. What is the price that a
student should pay (including VAT) for a Sunday purchase?

Answers

Answer:

£1009.8

Step-by-step explanation:

1) 1320/100*15= 13.2*15= 198- Sunday discount,

2) 1320-198=1122- The value with Sunday discount,

3) 1122/100*10= 112.2 - the student's discount,

4) 1122-112.2= 1009.8

The student paid £990 for the purchase of the laptop.

An equation is used to show the relationship between two or more numbers and variables.

The student purchase the laptop on a Sunday, hence:

Total discount = 15% + 10% = 25%

The laptop usually sells for £1320. Hence:

Discount = 25% of £1320 = 0.25 * 1320 = £330

Price paid by the student = £1320 - £330 = £990

The student paid £990 for the purchase of the laptop.
