Question

Do you want an overestimate or an underestimate when you estimate the total cost of items you want to buy? Explain

Answer 1

Easy all you have to do it estimate.  Example:  $11.62 + $7.86 = $19.48
$11.62 rounds to 12 and $7.80 rounds to $8.00 so the round to the total would be 20 so this would be an over estimate
