Irene bought some fruits. She spent $20 more than
23 of her money on some peaches. She then spent $6 more than 20% of the remaining money on some grapefruits. Given that she had $18 left,
- How much did Irene have at first?
- How many kilograms of grapefruits did she buy if they cost $2 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 18 + 6
= 24
1% of remaining money
= 24 ÷ 80
= 0.3
100% of remaining money
= 100 x 0.3
= 30
13 of total money
= 30 + 20
= $50
33 of total money
= 3 x 50
= $150
Amount that Irene had at first = $150
(b)
20% of the remaining money
= 30 x 20%
= 30 x
20100 = $6
Amount spent on grapefruits
= 6 + 6
= $12
Weight of grapefruits bought
= 12 ÷ 2
= 6 kg
Answer(s): (a) $150; (b) 6 kg
