Adam has some money to buy some stickers.
If he buys 3 stickers, he will have $6 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 - 3
= 2
To buy 2 stickers, he needs to use $6 that is left and get an extra of $12.
Difference in the amount to pay in both scenarios
= 6 + 12
= $18
Adam needs $18 to buy 2 extra stickers .
Cost of 2 stickers = $18
Cost of 1 sticker = 18 ÷ 2 = $9
(b)
Amount that he has
= Cost of 3 stickers + 6
= 3 x 9 + 6
= 27 + 6
= $33
Answer(s): (a) $9; (b) $33
