Ivory bought some fruits. She spent $20 more than
23 of her money on some starfruits. She then spent $4 more than 10% of the remaining money on some lemons. Given that she had $14 left,
- How much did Ivory have at first?
- How many kilograms of lemons did she buy if they cost $2 per kg?
(a)
100% - 10% = 90%
90% of remaining money
= 14 + 4
= 18
1% of remaining money
= 18 ÷ 90
= 0.2
100% of remaining money
= 100 x 0.2
= 20
13 of total money
= 20 + 20
= $40
33 of total money
= 3 x 40
= $120
Amount that Ivory had at first = $120
(b)
10% of the remaining money
= 20 x 10%
= 20 x
10100 = $2
Amount spent on lemons
= 4 + 2
= $6
Weight of lemons bought
= 6 ÷ 2
= 3 kg
Answer(s): (a) $120; (b) 4 kg
