Adam has some money to buy some stickers.
If he buys 8 stickers, he will have $13 left.
If he buys 16 stickers, he will need $11 more.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 16 - 8
= 8
To buy 8 stickers, he needs to use $13 that is left and get an extra of $11.
Difference in the amount to pay in both scenarios
= 13 + 11
= $24
Adam needs $24 to buy 8 extra stickers .
Cost of 8 stickers = $24
Cost of 1 sticker = 24 ÷ 8 = $3
(b)
Amount that he has
= Cost of 8 stickers + 13
= 8 x 3 + 13
= 24 + 13
= $37
Answer(s): (a) $3; (b) $37
