She bought 3 pomegranates, 6 kg of peaches and 2 kg of grapefruits. She paid a total of $53.40 for them. Find the cost of 100 g of grapefruits in cents.
Cost of the pomegranates
= 3 x 5
= $15
Cost of the peaches
= 6 x 4.60
= $27.60
Cost of the grapefruits
= 53.40 - 27.60 - 15
= $10.80
1 kg = 1000 g
2 kg = 2000 g
Number of sets of 100 g
= 2000 ÷ 100
= 20
2000 g = 20 sets of 100 g
Cost of 100 g of grapefruits
= 10.80 ÷ 20
= $0.54
$1 = 100¢
$0.54 = 54¢
Answer(s): 54¢
