7. Martin sells cars. He earns $100 per day, plus

any commission on his sales. His daily salary s in

dollars depends on the amount of commission c.

Write an equation to represent his daily salary.

S = 100 + C

S is his daily salary, what you're trying to find.

We know he makes $100 per day, so that'll be part of our equation.

In addition to $100, he makes commission on his sales daily. Since there is no defined amount for these commissions, we use c.

So, he makes $100 + the value of c every day.

Answer:the equation representing his daily salary is

s = 100 + c

Step-by-step explanation:

Let s represent the Salary that Martins earns per day.

Let c represent the commission that Martins earns on his sales on that day.

He earns $100 per day, plus

any commission on his sales. Since

his daily salary in dollars depends on the amount of commission, then an equation to represent his daily salary would be

s = 100 + c
