6.3 Percent Equation Objective: Today we want to be able to identify the percent equation. We will also learn how to use the equation to solve percent problems.

Information Percent equation: a = p% x b A = part B = base (total) P = percent

Finding part of base a = p% x b What number is 16% of 75? What number is 89% of 110?

Finding part of base-st a = p% x b What number is 60% of 25? What number is 20% of 45? What number is 10% of 56? What number is 150% of 96?

Find percent a = p% x b What percent of 25 is 60?

Find percent – st a = p% x b What percent of 500 is 12? What percent of 200 is 1? What percent of 80 is 212? What percent of 90 is 72?

Find base a = p% x b 27 is 7.5% of what number?

Find base – st a = p% x b 9 is .03% of what number?

Find commission Salesman makes 6.5% of every car sold. Sold one for $23,000. What’s his commission? Person earns 4% on sales. Sold total of $7000. What’s his commission?
