Adam has some money to buy some stickers.
If he buys 9 stickers, he will have $14 left.
If he buys 19 stickers, he will need $6 more.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 19 - 9
= 10
To buy 10 stickers, he needs to use $14 that is left and get an extra of $6.
Difference in the amount to pay in both scenarios
= 14 + 6
= $20
Adam needs $20 to buy 10 extra stickers .
Cost of 10 stickers = $20
Cost of 1 sticker = 20 ÷ 10 = $2
(b)
Amount that he has
= Cost of 9 stickers + 14
= 9 x 2 + 14
= 18 + 14
= $32
Answer(s): (a) $2; (b) $32
