100 divided by 50 is 2.
So multiply the change by 2, so 2 times 3.
Answer is 6 percent.
You have to take the amount of money payed, which in this case is 45.50, and divide it with 7.
Well is the length is 4 ft, and 1 ft is 12 inches we need to do 12×4, which is 48.
So now we know that the length is 48, and the height is 4, so it would be 48×4, which gives us our answer, 192 inches!
The sum of any integer and its opposite is equal to zero
Hope this helps :)
