PLEASE HELP ASAP
gayaneshka [121]

Answer:

<h3>Part A</h3>

<u>4 CD's cost $30.40, so one CD costs:</u>

  • 4p = $30.40
  • p = $30.40/4
  • p = $7.60
<h3>Part B</h3>

80% of the regular price is $7.60

<u>If the regular price is r, we have:</u>

  • 0.8r = $7.60
  • r = $7.60/0.8
  • r = $9.5

<u>3 CD's at regular price cost:</u>

  • $9.5*3 = $28.5

Since $25 < $28.5, we can't buy 3 more CD's.

<h3>Part C</h3>

The equation of a lone is 3/5x + 1/3y = 1/15
Maru [420]

Answer:

Step-by-step explanation:

x intercept is where the line is crossing the x axis or where y=0

y intercept is where the line crosses the y axis or where x=0

to find them, set other ting to zero

3/5x+1/3y=1/15

xintercept, set y=0

3/5x+1/3(0)=1/15

3/5x+0=1/15

3/5x=1/15

times 5/3 both sides

x=1/9

xintercept is x=1/9

yintercet

set x=0

3/5(0)+1/3y=1/15

0+1/3y=1/15

1/3y=1/15

times 3/1 both sides

y=1/5

yintercept is y=1/5

xint is x=1/9

yint is y=1/5

All books in a store are being discounted by 30%
Dafna11 [192]
Part A: 0.7(x)

Part B: 8.96/0.7 ---> (You can solve this by yourself)


For getting the answer, you can assume the regular price of the book is x. Then, the sale price would be x-0.3x, which is 0.7x

For part B, the price is 0.7 of the original. Dividing the number by 0.7 gets you the original price
