Xandra bought some fruits. She spent $15 more than
23 of her money on some lemons. She then spent $9 more than 30% of the remaining money on some pears. Given that she had $26 left,
- How much did Xandra have at first?
- How many kilograms of pears did she buy if they cost $2 per kg?
(a)
100% - 30% = 70%
70% of remaining money
= 26 + 9
= 35
1% of remaining money
= 35 ÷ 70
= 0.5
100% of remaining money
= 100 x 0.5
= 50
13 of total money
= 50 + 15
= $65
33 of total money
= 3 x 65
= $195
Amount that Xandra had at first = $195
(b)
30% of the remaining money
= 50 x 30%
= 50 x
30100 = $15
Amount spent on pears
= 9 + 15
= $24
Weight of pears bought
= 24 ÷ 2
= 12 kg
Answer(s): (a) $195; (b) 9 kg
