Opal bought some fruits. She spent $13 more than
45 of her money on some starfruits. She then spent $8 more than 10% of the remaining money on some kiwis. Given that she had $28 left,
- How much did Opal have at first?
- How many kilograms of kiwis did she buy if they cost $4 per kg?
(a)
100% - 10% = 90%
90% of remaining money
= 28 + 8
= 36
1% of remaining money
= 36 ÷ 90
= 0.4
100% of remaining money
= 100 x 0.4
= 40
15 of total money
= 40 + 13
= $53
55 of total money
= 5 x 53
= $265
Amount that Opal had at first = $265
(b)
10% of the remaining money
= 40 x 10%
= 40 x
10100 = $4
Amount spent on kiwis
= 8 + 4
= $12
Weight of kiwis bought
= 12 ÷ 4
= 3 kg
Answer(s): (a) $265; (b) 8 kg
