To increase an amount by 15 percent, you should multiply it by 1.15. This is because 1 represents the original amount, and 0.15 represents the 15 percent increase. For example, if you have an amount of $100, multiplying it by 1.15 results in $115, which reflects the 15 percent increase.
To calculate 15 percent off 150, first find 15 percent of 150 by multiplying 150 by 0.15, which equals 22.5. Then, subtract this amount from 150: 150 - 22.5 = 127.5. Therefore, 15 percent off 150 is 127.5.
First find 10% by dividing the total amount by 10. So 10% of 15 = 1.5 Now subtract 10% from the original amount to get 15 - 1.5 = 13.5
17.85
.15x = 6 Divide both sides by .15 6/.15 = 40 15 percent of 40 is 6.
