Adam has some money to buy some stickers.
If he buys 2 stickers, he will have $15 left.
If he buys 5 stickers, he will need $12 more.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 5 - 2
= 3
To buy 3 stickers, he needs to use $15 that is left and get an extra of $12.
Difference in the amount to pay in both scenarios
= 15 + 12
= $27
Adam needs $27 to buy 3 extra stickers .
Cost of 3 stickers = $27
Cost of 1 sticker = 27 ÷ 3 = $9
(b)
Amount that he has
= Cost of 2 stickers + 15
= 2 x 9 + 15
= 18 + 15
= $33
Answer(s): (a) $9; (b) $33
