Question

A salesperson is paid $140 per week plus 10% commission on her weekly sales of x dollars. Find a linear function that represents her total weekly pay w in terms of x.

Answer 1

Her weekly sales is X dollars

10% as a decimal is 0.10

Total commission is 0.10X ( 10% times weekly sales)

You then need to add that to her base pay of $140.

The equation is: w = 0.10x + 140
