Answer: 60%
Explanation:
Hi, to answer this question we have to write an equation with the information given:
The price of an item yesterday multiplied by the increase is equal to today's price:
135 x = 216
x =216/135
X=1.6
The percent increase is 60%.
Because:
1.6 = 1+ 0.6 (where 1 is the original price and 0.6 is the increase in decimal form)
0.6 x 100 = 60%
