This equation can be expressed as: abs(55- 4x) = 15, where abs = absolute value. x can equal 10 or 17.5.
To find 7 percent of a number, multiply the number by 0.07. In this instance, 0.07 x 57140 = 3999.8. Therefore, 7 percent of 57140 is equal to 3999.8.
To find 2 percent of a number, multiply that number by 0.02. In this instance, 7000 x 0.02 = 140. Therefore, 2 percent of 7000 is equal to 140.
