Adam has some money to buy some stickers.
If he buys 10 stickers, he will have $5 left.
If he buys 14 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
= 14 - 10
= 4
To buy 4 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 4 extra stickers .
Cost of 4 stickers = $16
Cost of 1 sticker = 16 ÷ 4 = $4
(b)
Amount that he has
= Cost of 10 stickers + 5
= 10 x 4 + 5
= 40 + 5
= $45
Answer(s): (a) $4; (b) $45
