Answer:
1 banana = + $0.25
2 bananas = + $0.50
Explanation:
If it is increasing %0.50 for every 2 bananas then that also means it's increasing $0.25 for every 1 banana.
1 banana = 0.25
Find the proportion. Simply divide the cost from the amount of bananas given:
0.50/2 = 0.25
1.00/4 = 0.25
1.50/6 = 0.25
$0.25 is the cost per banana, and is your proportion.
