Adam has some money to buy some stickers.
If he buys 5 stickers, he will have $12 left.
If he buys 11 stickers, he will need $6 more.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 11 - 5
= 6
To buy 6 stickers, he needs to use $12 that is left and get an extra of $6.
Difference in the amount to pay in both scenarios
= 12 + 6
= $18
Adam needs $18 to buy 6 extra stickers .
Cost of 6 stickers = $18
Cost of 1 sticker = 18 ÷ 6 = $3
(b)
Amount that he has
= Cost of 5 stickers + 12
= 5 x 3 + 12
= 15 + 12
= $27
Answer(s): (a) $3; (b) $27
