Irene bought some fruits. She spent $18 more than
56 of her money on some lemons. She then spent $5 more than 20% of the remaining money on some pomegranates. Given that she had $15 left,
- How much did Irene have at first?
- How many kilograms of pomegranates did she buy if they cost $5 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 15 + 5
= 20
1% of remaining money
= 20 ÷ 80
= 0.25
100% of remaining money
= 100 x 0.25
= 25
16 of total money
= 25 + 18
= $43
66 of total money
= 6 x 43
= $258
Amount that Irene had at first = $258
(b)
20% of the remaining money
= 25 x 20%
= 25 x
20100 = $5
Amount spent on pomegranates
= 5 + 5
= $10
Weight of pomegranates bought
= 10 ÷ 5
= 2 kg
Answer(s): (a) $258; (b) 5 kg
