Answer:
20%
Step-by-step explanation:
Here, we want to calculate the percentage increase in the price of a can of green beans
Mathematically, we use the formula below;
(new price - old price)/old price * 100%
From the question;
old price = $0.50
new price = $0.60
So we have;
(0.6-0.5)/0.5 * 100%
= 0.1/0.5 * 100%
= 20%
