Question

Chris bought 39 items at a yard sale for $9.75 each. About how much did he spend in all? (Use estimation)

Answer 1

$390

Explanation:

If you are going to estimate, you should round to the nearest one (for a whole number answer), so we would round $9.75 to $10.

39*$10 = 390

Estimate: $390

Exact answer: $380.25
