Adam has some money to buy some stickers.
If he buys 8 stickers, he will have $14 left.
If he buys 10 stickers, he will need $8 more.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 10 - 8
= 2
To buy 2 stickers, he needs to use $14 that is left and get an extra of $8.
Difference in the amount to pay in both scenarios
= 14 + 8
= $22
Adam needs $22 to buy 2 extra stickers .
Cost of 2 stickers = $22
Cost of 1 sticker = 22 ÷ 2 = $11
(b)
Amount that he has
= Cost of 8 stickers + 14
= 8 x 11 + 14
= 88 + 14
= $102
Answer(s): (a) $11; (b) $102
