She bought 2 grapefruits, 6 kg of mangosteens and 6 kg of starfruits. She paid a total of $47.80 for them. Find the cost of 100 g of starfruits in cents.
Cost of the grapefruits
= 2 x 2
= $4
Cost of the mangosteens
= 6 x 4.90
= $29.40
Cost of the starfruits
= 47.80 - 29.40 - 4
= $14.40
1 kg = 1000 g
6 kg = 6000 g
Number of sets of 100 g
= 6000 ÷ 100
= 60
6000 g = 60 sets of 100 g
Cost of 100 g of starfruits
= 14.40 ÷ 60
= $0.24
$1 = 100¢
$0.24 = 24¢
Answer(s): 24¢
