Lucy bought some fruits. She spent $12 more than
34 of her money on some pears. She then spent $4 more than 20% of the remaining money on some starfruits. Given that she had $28 left,
- How much did Lucy have at first?
- How many kilograms of starfruits did she buy if they cost $3 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 28 + 4
= 32
1% of remaining money
= 32 ÷ 80
= 0.4
100% of remaining money
= 100 x 0.4
= 40
14 of total money
= 40 + 12
= $52
44 of total money
= 4 x 52
= $208
Amount that Lucy had at first = $208
(b)
20% of the remaining money
= 40 x 20%
= 40 x
20100 = $8
Amount spent on starfruits
= 4 + 8
= $12
Weight of starfruits bought
= 12 ÷ 3
= 4 kg
Answer(s): (a) $208; (b) 4 kg
