Question

a worker makes 30000 a year. after 1 year he gets a raise of 5%. the next year he gets a raise of 10%. If he received no raise the first year, what percent increase would give him the same salary as consecutive raises of 5% and 10%?

would it be 50%

Answer 1

Nope! A 50% increase would give him a salary of $45,000.

30,000 * 1.05 = 31,500

31,500 * 1.1 = 34,650

34,650 - 30,000 = 4650

4,650/30,000 = 0.155 = 15.5%

Answer 2

what number is between 0.1 and 0.24
