Cindy bought some fruits. She spent $10 more than
56 of her money on some dragonfruits. She then spent $8 more than 30% of the remaining money on some peaches. Given that she had $20 left,
- How much did Cindy have at first?
- How many kilograms of peaches did she buy if they cost $5 per kg?
(a)
100% - 30% = 70%
70% of remaining money
= 20 + 8
= 28
1% of remaining money
= 28 ÷ 70
= 0.4
100% of remaining money
= 100 x 0.4
= 40
16 of total money
= 40 + 10
= $50
66 of total money
= 6 x 50
= $300
Amount that Cindy had at first = $300
(b)
30% of the remaining money
= 40 x 30%
= 40 x
30100 = $12
Amount spent on peaches
= 8 + 12
= $20
Weight of peaches bought
= 20 ÷ 5
= 4 kg
Answer(s): (a) $300; (b) 8 kg
