Question

Abit is planning a birthday party for his grandfather. He bought a cake for $18. He also wants to buy some balloons, which are $4 each. Abit has $35 to spend all together. How much money will Abit have left after he buys the cake and as many balloons as possible?

Answer 1

Total = $35

After buying the cake,
$35 - $18 = $17

Number of balloons he can buy:
17 ÷ 4 = 4.25
So, he can buy 4 balloons.

4 ballons = 4x4 = $16
So amount left  = $17 - $16 = $1

Answer 2

35 - 18 = 17
The number 4 can fit into the number 17 4 times. 4 x 4 = 16

Therefore, Abit will only have $1 left over.
