Question

A local pizza shop has a membership program for frequent buyers. The membership costs $20 per month and members get a discounted price of $1.50 per slice of pizza. Shandra purchased a membership to this pizza shop. How much would Shandra have to pay the pizza shop if she bought 5 slices of pizza this month? What would be the monthly cost for x slices of pizza?

Answer 1

Answer:

Shandra would pay $27.50 for 5 slices

Cost = 20+1.50x

Step-by-step explanation:

Given

$Membership = \ 20$

$Discounted\ Price = \ 1.50$ per slice

Solving (a): Cost of 5 slices

Represent the total price with y and the number of slice with x.

So, we have:

$y = Membership + Discounted\ Price * x$

This gives:

$y = 20+ 1.50* x$

In this case: x = 5.

So, we have:

$y = 20+ 1.50* 5$

$y = 20+ 7.50$

$y = 27.50$

Shandra would pay $27.50 for 5 slices

Solving (b): Cost of x slices

This has been solved in (a).

$y = 20+ 1.50* x$

$y = 20+1.50x$

Hence, the cost of x slices is 20+1.50x
