Eva had some money. If she buys 8 lollipops, she will have $7 left. If she buys 10 lollipops, she will have $3 left.
- How much does each lollipop cost?
- How much money does she have?
(a)
Let 1 L be the price of 1 lollipop.
8 L + 7 = 10 L + 3
10 L - 8 L = 7 - 3
2 L = 4
1 L = 4 ÷ 2 = 2
Cost of each lollipop = $2
(b)
Total amount that Eva had
= 10 x 2 + 3
= 20 + 3
= $23
Answer(s): (a) $2; (b) $23
