Another way to write this algebric expression?

Question

What is another way to write this expression?

Prices for renting videos:

New Release: 4.49

Old Release: 2.99

To BUY a new video: 9.99

The clerk rents 3 new releases, rent 2 old releases, and buys 5 new videos. Write 2 algebric expressions for this problem.

I have:

3(4.49) + 2(2.99) + 5(9.99)

What is another way?

Answer 1

Total = T

NR = x

OR = y

Buy = z

T = 4.49x + 2.99y + 9.99z

or

Total = T

NR = x

OR = (x - 1.50)

Buy = (x + 5.50)

T = 3x + 2(x - 1.50) + 5(x + 5.50)

I hope this helps.  Keep smilin
