Shannon bought some fruits. She spent $11 more than
23 of her money on some mangoes. She then spent $9 more than 20% of the remaining money on some starfruits. Given that she had $19 left,
- How much did Shannon have at first?
- How many kilograms of starfruits did she buy if they cost $2 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 19 + 9
= 28
1% of remaining money
= 28 ÷ 80
= 0.35
100% of remaining money
= 100 x 0.35
= 35
13 of total money
= 35 + 11
= $46
33 of total money
= 3 x 46
= $138
Amount that Shannon had at first = $138
(b)
20% of the remaining money
= 35 x 20%
= 35 x
20100 = $7
Amount spent on starfruits
= 9 + 7
= $16
Weight of starfruits bought
= 16 ÷ 2
= 8 kg
Answer(s): (a) $138; (b) 9 kg
