Anton Greene · Answer 1

Step-by-step explanation:

A. round each price to the nearest dollar:

4.85 - 5.00

5.06 - 5.00

1.39 - 1.00

2.13 - 2.00

6.70 - 7.00

9.61 - 10.00

3.29 - 3.00

$33.00

B. My estimate is comes out to be $30.00 which is $0.48 short of the total that the register shows. Therefore, $30.48 is very reasonable, you only need $0.48 more to pay for all your groceries
