She bought 4 dragonfruits, 4 kg of guavas and 5 kg of grapefruits. She paid a total of $52.10 for them. Find the cost of 100 g of grapefruits in cents.
Cost of the dragonfruits
= 4 x 2
= $8
Cost of the guavas
= 4 x 4.90
= $19.60
Cost of the grapefruits
= 52.10 - 19.60 - 8
= $24.50
1 kg = 1000 g
5 kg = 5000 g
Number of sets of 100 g
= 5000 ÷ 100
= 50
5000 g = 50 sets of 100 g
Cost of 100 g of grapefruits
= 24.50 ÷ 50
= $0.49
$1 = 100¢
$0.49 = 49¢
Answer(s): 49¢
