Adam has some money to buy some stickers.
If he buys 6 stickers, he will have $5 left.
If he buys 8 stickers, he will need $9 more.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 8 - 6
= 2
To buy 2 stickers, he needs to use $5 that is left and get an extra of $9.
Difference in the amount to pay in both scenarios
= 5 + 9
= $14
Adam needs $14 to buy 2 extra stickers .
Cost of 2 stickers = $14
Cost of 1 sticker = 14 ÷ 2 = $7
(b)
Amount that he has
= Cost of 6 stickers + 5
= 6 x 7 + 5
= 42 + 5
= $47
Answer(s): (a) $7; (b) $47
