Adam has some money to buy some stickers.
If he buys 6 stickers, he will have $14 left.
If he buys 15 stickers, he will need $4 more.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 15 - 6
= 9
To buy 9 stickers, he needs to use $14 that is left and get an extra of $4.
Difference in the amount to pay in both scenarios
= 14 + 4
= $18
Adam needs $18 to buy 9 extra stickers .
Cost of 9 stickers = $18
Cost of 1 sticker = 18 ÷ 9 = $2
(b)
Amount that he has
= Cost of 6 stickers + 14
= 6 x 2 + 14
= 12 + 14
= $26
Answer(s): (a) $2; (b) $26
