Emma bought some fruits. She spent $16 more than
45 of her money on some peaches. She then spent $5 more than 20% of the remaining money on some chikoos. Given that she had $23 left,
- How much did Emma have at first?
- How many kilograms of chikoos did she buy if they cost $4 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 23 + 5
= 28
1% of remaining money
= 28 ÷ 80
= 0.35
100% of remaining money
= 100 x 0.35
= 35
15 of total money
= 35 + 16
= $51
55 of total money
= 5 x 51
= $255
Amount that Emma had at first = $255
(b)
20% of the remaining money
= 35 x 20%
= 35 x
20100 = $7
Amount spent on chikoos
= 5 + 7
= $12
Weight of chikoos bought
= 12 ÷ 4
= 3 kg
Answer(s): (a) $255; (b) 5 kg
