His total earnings last year is: $ 36,732
It is given that:
An insurance salesman earns a base pay of $31,700 per year and a commission of 17% of all sales made.
If he sold $29,600 worth of products last year.
This means that the commission on the sales will be:
17% of 29,600
= 0.17 of 29,600
= 0.17×29,600
= $ 5,032
Hence, the total earnings he made last year= Base pay+Commission on sales made.
i.e.
Total earning= 31,700+5,032
i.e.
Total earning= $ 36,732
