Adam has some money to buy some stickers.
If he buys 4 stickers, he will have $6 left.
If he buys 6 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
= 6 - 4
= 2
To buy 2 stickers, he needs to use $6 that is left and get an extra of $2.
Difference in the amount to pay in both scenarios
= 6 + 2
= $8
Adam needs $8 to buy 2 extra stickers .
Cost of 2 stickers = $8
Cost of 1 sticker = 8 ÷ 2 = $4
(b)
Amount that he has
= Cost of 4 stickers + 6
= 4 x 4 + 6
= 16 + 6
= $22
Answer(s): (a) $4; (b) $22
