Erika bought some fruits. She spent $14 more than
23 of her money on some mangosteens. She then spent $8 more than 20% of the remaining money on some peaches. Given that she had $16 left,
- How much did Erika have at first?
- How many kilograms of peaches did she buy if they cost $2 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 16 + 8
= 24
1% of remaining money
= 24 ÷ 80
= 0.3
100% of remaining money
= 100 x 0.3
= 30
13 of total money
= 30 + 14
= $44
33 of total money
= 3 x 44
= $132
Amount that Erika had at first = $132
(b)
20% of the remaining money
= 30 x 20%
= 30 x
20100 = $6
Amount spent on peaches
= 8 + 6
= $14
Weight of peaches bought
= 14 ÷ 2
= 7 kg
Answer(s): (a) $132; (b) 8 kg
