Charlie has some money to buy some stickers.
If he buys 10 stickers, he will have $19 left.
If he buys 14 stickers, he will have $11 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 14 - 10
= 4
Difference in the amount to pay in both scenarios
= 19 - 11
= 8
Charlie needs $8 to buy 4 extra stickers.
Cost of 4 stickers = $8
Cost of 1 sticker = 8 ÷ 4 = $2
(b)
Amount that he has
= Cost of 10 stickers + 19
= 10 x 2 + 19
= 20 + 19
= $39
Answer(s): (a) $2; (b) $39
