Xylia had some money. If she buys 5 chocolate bars, she will have $10 left. If she buys 8 chocolate bars, she will have $1 left.
- How much does each chocolate bar cost?
- How much money does she have?
(a)
Let 1 C be the price of 1 chocolate bar.
5 C + 10 = 8 C + 1
8 C - 5 C = 10 - 1
3 C = 9
1 C = 9 ÷ 3 = 3
Cost of each chocolate bar = $3
(b)
Total amount that Xylia had
= 8 x 3 + 1
= 24 + 1
= $25
Answer(s): (a) $3; (b) $25
