Tammy bought some fruits. She spent $15 more than
34 of her money on some starfruits. She then spent $4 more than 20% of the remaining money on some chikoos. Given that she had $16 left,
- How much did Tammy have at first?
- How many kilograms of chikoos did she buy if they cost $3 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 16 + 4
= 20
1% of remaining money
= 20 ÷ 80
= 0.25
100% of remaining money
= 100 x 0.25
= 25
14 of total money
= 25 + 15
= $40
44 of total money
= 4 x 40
= $160
Amount that Tammy had at first = $160
(b)
20% of the remaining money
= 25 x 20%
= 25 x
20100 = $5
Amount spent on chikoos
= 4 + 5
= $9
Weight of chikoos bought
= 9 ÷ 3
= 3 kg
Answer(s): (a) $160; (b) 4 kg
