Gwen bought some fruits. She spent $16 more than
23 of her money on some pomegranates. She then spent $7 more than 30% of the remaining money on some mangosteens. Given that she had $28 left,
- How much did Gwen have at first?
- How many kilograms of mangosteens did she buy if they cost $2 per kg?
(a)
100% - 30% = 70%
70% of remaining money
= 28 + 7
= 35
1% of remaining money
= 35 ÷ 70
= 0.5
100% of remaining money
= 100 x 0.5
= 50
13 of total money
= 50 + 16
= $66
33 of total money
= 3 x 66
= $198
Amount that Gwen had at first = $198
(b)
30% of the remaining money
= 50 x 30%
= 50 x
30100 = $15
Amount spent on mangosteens
= 7 + 15
= $22
Weight of mangosteens bought
= 22 ÷ 2
= 11 kg
Answer(s): (a) $198; (b) 7 kg
