Adam has some money to buy some stickers.
If he buys 10 stickers, he will have $5 left.
If he buys 12 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
= 12 - 10
= 2
To buy 2 stickers, he needs to use $5 that is left and get an extra of $11.
Difference in the amount to pay in both scenarios
= 5 + 11
= $16
Adam needs $16 to buy 2 extra stickers .
Cost of 2 stickers = $16
Cost of 1 sticker = 16 ÷ 2 = $8
(b)
Amount that he has
= Cost of 10 stickers + 5
= 10 x 8 + 5
= 80 + 5
= $85
Answer(s): (a) $8; (b) $85
