Xylia bought some fruits. She spent $18 more than
34 of her money on some peaches. She then spent $9 more than 30% of the remaining money on some grapefruits. Given that she had $26 left,
- How much did Xylia have at first?
- How many kilograms of grapefruits did she buy if they cost $3 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
14 of total money
= 50 + 18
= $68
44 of total money
= 4 x 68
= $272
Amount that Xylia had at first = $272
(b)
30% of the remaining money
= 50 x 30%
= 50 x
30100 = $15
Amount spent on grapefruits
= 9 + 15
= $24
Weight of grapefruits bought
= 24 ÷ 3
= 8 kg
Answer(s): (a) $272; (b) 9 kg
