Answer 4

So for part a, it's asking for an expression:
`r - 5` where r is the regular price.
For b, it wants you to make this a function and incorporate the tax:
`p(r) = (r - 5)*(1 + tax)`
For c, you're simply inserting the numbers for r = 15.50 and tax = 0.05

Answer 6

Ok so do you get $11.02 for the c. part ?

Answer 7

Well if you plug it in you'll find:
`p(15.50) = (15.50 - 5)*(1 + 0.05)` = `(10.5) * (1.05)` = `$11.025`
