Adam has some money to buy some stickers.
If he buys 4 stickers, he will have $6 left.
If he buys 8 stickers, he will need $10 more.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 8 - 4
= 4
To buy 4 stickers, he needs to use $6 that is left and get an extra of $10.
Difference in the amount to pay in both scenarios
= 6 + 10
= $16
Adam needs $16 to buy 4 extra stickers .
Cost of 4 stickers = $16
Cost of 1 sticker = 16 ÷ 4 = $4
(b)
Amount that he has
= Cost of 4 stickers + 6
= 4 x 4 + 6
= 16 + 6
= $22
Answer(s): (a) $4; (b) $22
