Eva had some money. If she buys 8 sweets, she will have $8 left. If she buys 11 sweets, she will have $2 left.
- How much does each sweet cost?
- How much money does she have?
(a)
Let 1 S be the price of 1 sweet.
8 S + 8 = 11 S + 2
11 S - 8 S = 8 - 2
3 S = 6
1 S = 6 ÷ 3 = 2
Cost of each sweet = $2
(b)
Total amount that Eva had
= 11 x 2 + 2
= 22 + 2
= $24
Answer(s): (a) $2; (b) $24
