Rachel bought some fruits. She spent $12 more than
23 of her money on some lemons. She then spent $6 more than 20% of the remaining money on some dragonfruits. Given that she had $26 left,
- How much did Rachel have at first?
- How many kilograms of dragonfruits did she buy if they cost $2 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 26 + 6
= 32
1% of remaining money
= 32 ÷ 80
= 0.4
100% of remaining money
= 100 x 0.4
= 40
13 of total money
= 40 + 12
= $52
33 of total money
= 3 x 52
= $156
Amount that Rachel had at first = $156
(b)
20% of the remaining money
= 40 x 20%
= 40 x
20100 = $8
Amount spent on dragonfruits
= 6 + 8
= $14
Weight of dragonfruits bought
= 14 ÷ 2
= 7 kg
Answer(s): (a) $156; (b) 6 kg
