Marion bought some fruits. She spent $11 more than
23 of her money on some kiwis. She then spent $8 more than 20% of the remaining money on some grapefruits. Given that she had $24 left,
- How much did Marion 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
= 24 + 8
= 32
1% of remaining money
= 32 ÷ 80
= 0.4
100% of remaining money
= 100 x 0.4
= 40
13 of total money
= 40 + 11
= $51
33 of total money
= 3 x 51
= $153
Amount that Marion had at first = $153
(b)
20% of the remaining money
= 40 x 20%
= 40 x
20100 = $8
Amount spent on grapefruits
= 8 + 8
= $16
Weight of grapefruits bought
= 16 ÷ 2
= 8 kg
Answer(s): (a) $153; (b) 8 kg
