Answer:

Shandra would pay $27.50 for 5 slices

Cost = 20+1.50x

Step-by-step explanation:

Given

[tex]Membership = \$20[/tex]

[tex]Discounted\ Price = \$1.50[/tex] per slice

Solving (a): Cost of 5 slices

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

So, we have:

[tex]y = Membership + Discounted\ Price * x[/tex]

This gives:

[tex]y = 20+ 1.50* x[/tex]

In this case: x = 5.

So, we have:

[tex]y = 20+ 1.50* 5[/tex]

[tex]y = 20+ 7.50[/tex]

[tex]y = 27.50[/tex]

Shandra would pay $27.50 for 5 slices

Solving (b): Cost of x slices

This has been solved in (a).

[tex]y = 20+ 1.50* x[/tex]

[tex]y = 20+1.50x[/tex]

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