Adam has some money to buy some stickers.
If he buys 2 stickers, he will have $13 left.
If he buys 5 stickers, he will need $2 more.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 5 - 2
= 3
To buy 3 stickers, he needs to use $13 that is left and get an extra of $2.
Difference in the amount to pay in both scenarios
= 13 + 2
= $15
Adam needs $15 to buy 3 extra stickers .
Cost of 3 stickers = $15
Cost of 1 sticker = 15 ÷ 3 = $5
(b)
Amount that he has
= Cost of 2 stickers + 13
= 2 x 5 + 13
= 10 + 13
= $23
Answer(s): (a) $5; (b) $23
