Sasha Bush · Answer 1

32.85+24.30 = $57.15 is the amount needed to buy the jacket and mitten

he has saved 45

so 57.15-45=12.15

he needs 12.15 more dollars

For an estimation, we round these numbers.

32.85 rounds up to 33

and 24.30 rounds down to 24

33+24=57

57-45=12

he needs around $12

so the correct answer is A
