She bought 4 persimmons, 2 kg of passion fruits and 5 kg of mangosteens. She paid a total of $71.70 for them. Find the cost of 100 g of mangosteens in cents.
Cost of the persimmons
= 4 x 1
= $4
Cost of the passion fruits
= 2 x 3.10
= $6.20
Cost of the mangosteens
= 71.70 - 6.20 - 4
= $61.50
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 mangosteens
= 61.50 ÷ 50
= $1.23
$1 = 100¢
$1.23 = 123¢
Answer(s): 123¢
