Kimberly had some money. If she buys 11 chocolate bars, she will have $9 left. If she buys 14 chocolate bars, she will have $3 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.
11 C + 9 = 14 C + 3
14 C - 11 C = 9 - 3
3 C = 6
1 C = 6 ÷ 3 = 2
Cost of each chocolate bar = $2
(b)
Total amount that Kimberly had
= 14 x 2 + 3
= 28 + 3
= $31
Answer(s): (a) $2; (b) $31
