Question

a computer store buys a computer for $24 and sells it for $91.20 .what is the percent of increase in the price?pls someone help me!

Answer 1

The answer would be 280% 

First, you find the increase by subtracting the two numbers 
91.20-24=67.2

Then, take the increase and divide it by the original number 
67.2/24= 2.8 

Finally, multiply by 100
2.8 * 100= 280%
