Answer 1

I don't have the rest of the problem — I need the items, prices, quantities, tax or discount information from the original question. Please paste the full problem text or give those details.

If you want examples of how to write the expression, here are templates you can adapt (no $ signs, as requested):

- If Mrs. Peabody buys a items at $p each and b items at $q each: p*a + q*b
- If there is a sales tax r (as a decimal) on the subtotal: (p*a + q*b) * (1 + r)
- If there is a coupon of c dollars off the subtotal: p*a + q*b - c

Send the specific numbers/variables and I will write the exact expression.
