She bought 6 chikoos, 3 kg of lemons and 4 kg of starfruits. She paid a total of $39.40 for them. Find the cost of 100 g of starfruits in cents.
Cost of the chikoos
= 6 x 4
= $24
Cost of the lemons
= 3 x 3.40
= $10.20
Cost of the starfruits
= 39.40 - 10.20 - 24
= $5.20
1 kg = 1000 g
4 kg = 4000 g
Number of sets of 100 g
= 4000 ÷ 100
= 40
4000 g = 40 sets of 100 g
Cost of 100 g of starfruits
= 5.20 ÷ 40
= $0.13
$1 = 100¢
$0.13 = 13¢
Answer(s): 13¢
