She bought 3 pears, 4 kg of starfruits and 5 kg of grapefruits. She paid a total of $74.70 for them. Find the cost of 100 g of grapefruits in cents.
Cost of the pears
= 3 x 5
= $15
Cost of the starfruits
= 4 x 1.30
= $5.20
Cost of the grapefruits
= 74.70 - 5.20 - 15
= $54.50
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
= 54.50 ÷ 50
= $1.09
$1 = 100¢
$1.09 = 109¢
Answer(s): 109¢
