Can someone else explain it but more easier for an 8th grader
In January, gasoline cost $1.05 per gallon. In July, gasoline cost $1.20 per gallon. Find the percent of increase.
Would the answer for this question be 14.3?
And how do you do percent of decrease?
The original cost of a computer is $900. If the price is decreased by 15%, what is the sale price?
I need help with this question(:
1.20 - 1.05 = 0.15
0.15 / 1.05 = 0.143 = 14% decrease
900 * 0.15 = 135
900 - 135 = 765
Kenya -- we have students posting upper level high school and college math. After this I suggest you use 8th grade math as your subject.
