Emily bought some fruits. She spent $19 more than
23 of her money on some pears. She then spent $7 more than 30% of the remaining money on some starfruits. Given that she had $14 left,
- How much did Emily have at first?
- How many kilograms of starfruits did she buy if they cost $2 per kg?
(a)
100% - 30% = 70%
70% of remaining money
= 14 + 7
= 21
1% of remaining money
= 21 ÷ 70
= 0.3
100% of remaining money
= 100 x 0.3
= 30
13 of total money
= 30 + 19
= $49
33 of total money
= 3 x 49
= $147
Amount that Emily had at first = $147
(b)
30% of the remaining money
= 30 x 30%
= 30 x
30100 = $9
Amount spent on starfruits
= 7 + 9
= $16
Weight of starfruits bought
= 16 ÷ 2
= 8 kg
Answer(s): (a) $147; (b) 7 kg
