Question

There are 24 children at the skate park. Seven of them are on bikes, nine of

them are on skateboards, and the rest are on inline skates (4 wheels per
skate). How many wheels are at the skate park?

Answer 1

114

Explanation:

9 + 7 = 16

24 - 16 = 8 students on inline skates

8 x 4 wheels per skate = 32

32 x 2 shoes per person = 64

7 x 2 wheels per bike = 14

9 x 4 wheels per skate board = 36

36 + 14 + 64 = 114

Answer 2

82 wheels

Explanation:

7(2) + 9(4) + 8(4) = x

14 + 36 + 32 = x

82 = x
