# Mrs. Barns earns a base salary of plus a 1.5% commission on sales. Her total sales one year were $700,000. How do you find her total pay for the year? ##### 1 Answer Jul 6, 2017 See a solution process below: #### Explanation: Mrs. Barns total salary can be written as: $t = b + \left(c \cdot s\right)$Where: $t$is Mrs. Barns total pay for the year $b$is Mrs. Barns base salary $c$is Mrs. Barns commission rate. In this problem: 1.5%. "Percent" or "%" means "out of 100" or "per 100", Therefore 1.5% can be written as $\frac{1.5}{100}$or $\frac{15}{1000}$. $s$is the total sales for the year. In this problem:$700,000

Substituting the information from the problem gives:

t = b + (15/1000 * $700,000) t = b + ($10,500,000)/1000

t = b + $10,500 Mrs. barns total pay would be the$10,500 from commissions plus her base salary.
