b.

c.

d.
The Changs family paid the correct amount for their purchase

Answer 1

Subtotal = 89.95 + 239.99 = 329.94.

If the sales tax is 6.5%: tax = 0.065 × 329.94 = 21.4461 → $21.45 (rounded to cents).
Total should be 329.94 + 21.45 = 351.39.

They actually paid 351.72, which is 351.72 − 351.39 = $0.33 too much.

Answer: a. The Changs family paid $0.33 too much.
