She bought 6 starfruits, 5 kg of pears and 5 kg of grapefruits. She paid a total of $50.50 for them. Find the cost of 100 g of grapefruits in cents.
Cost of the starfruits
= 6 x 3
= $18
Cost of the pears
= 5 x 1.40
= $7.00
Cost of the grapefruits
= 50.50 - 7.00 - 18
= $25.50
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
= 25.50 ÷ 50
= $0.51
$1 = 100¢
$0.51 = 51¢
Answer(s): 51¢
