Adam has some money to buy some stickers.
If he buys 3 stickers, he will have $5 left.
If he buys 11 stickers, he will need $3 more.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 11 - 3
= 8
To buy 8 stickers, he needs to use $5 that is left and get an extra of $3.
Difference in the amount to pay in both scenarios
= 5 + 3
= $8
Adam needs $8 to buy 8 extra stickers .
Cost of 8 stickers = $8
Cost of 1 sticker = 8 ÷ 8 = $1
(b)
Amount that he has
= Cost of 3 stickers + 5
= 3 x 1 + 5
= 3 + 5
= $8
Answer(s): (a) $1; (b) $8
