Question

Emma's grandmother sent her an $80 bookstore gift card for her birthday. Emma wants to make sure that her purchases don't exceed the amount of her gift card. So far, she has selected books that cost $8.95, $11.95, $22.25, and $24.95. She has also found a calendar she likes for $8.25. Round each item up to the next dollar to overestimate the total cost of the items in Emma's shopping basket.

Answer 1

Answer: 78$

Actual Estimate

$8.95 --------------------------$9.00

$11.95--------------------------$12.00

22.25--------------------------$23.00

$24.95------------------------$25.00

$8.25--------------------------$9.00

Then add the estimate numbers to get $78

Answer 2

Answer: total cost of the estimated items = $76

Explanation:

Step 1

Rounding up each item to the next dollar

Book 1 = $8.95 ≈ $9.00

Book 2 = $11.95≈ $12.00

Book 3 = $22.25≈$22.00

Book 4 = $24.95≈$25.00

Calendar = $8.25 ≈$8.00

Step 2

The total estimated cost of items in Emma's shopping basket =$9.00+$12.00+$22.00+$25.00+$8.00

=$76 which did not exceed the amount of bookstore gift card of $80 sent by her grandmother.
