1. At the grocery store checkout, you watch at the register as it rings up your purchases and coupons. The prices were as follows:

$2.95
$1.19
$4.61
$1.74
$3.04
$8.83
$1.16
– $0.75 (coupon)
– $1.00 (coupon)

The register gives your total bill as $21.77. Estimate the total amount of the bill and use your answer to determine whether the total on the register is reasonable.
Answer:

Answer 1

Answer: 3+1+5+2+3+9+1-1-1=22

The total on the register is reasonable because if you estimate $21.77 to the nearest dollar you would get $22.00.

Explanation:

Answer 2

estimate by rounded to the nearest dollars

2 +1 +5 +2 +3 +9 +1 = $23

-2

23-2 = 21

yes the amount is reasonable
