The number of oranges purchased by Evan using proportional relationship is 8 bags
Given the Parameters :
Cost of 7 bags of oranges = 2.10
Cost of oranges purchased = $2.40
To obtain the amount of oranges purchased, we can set up a proportional relationship thus :
7 bags = $2.10
x bags = $2.40
Cross multiply :
2.10x = 2.40 × 7
2.10x = 16.8
Divide both sides by 2.10 to isolate x
x = 16.8 / 2.10
x = 8
Hence, Evan bought 8 bags of oranges.
