She bought 6 mangoes, 3 kg of starfruits and 5 kg of persimmons. She paid a total of $56.20 for them. Find the cost of 100 g of persimmons in cents.
Cost of the mangoes
= 6 x 5
= $30
Cost of the starfruits
= 3 x 2.90
= $8.70
Cost of the persimmons
= 56.20 - 8.70 - 30
= $17.50
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 persimmons
= 17.50 ÷ 50
= $0.35
$1 = 100¢
$0.35 = 35¢
Answer(s): 35¢
