Sammy wanted to buy a bike to ride to swim team. The bike cost $115.85. Sammy had only saved $84.38. How much more did he need in order to buy the bike? (Do no add another $ sign - it is already there for the answer).

Answer 1

To find out how much more Sammy needs to buy the bike, we subtract the amount he has saved from the cost of the bike:

$115.85 - $84.38 = $31.47

Sammy needs $31.47 more to buy the bike.
