Dave receives a salary of $200 a week plus a commission of 10% of his weekly sales. an equation y=mx+b represents dave’s weekly earnings. the y-intercept is dave’s base salary. the slope of the line is his commission. write an equation representing dave’s weekly earnings. if dave sells $1500 of goods for one week, what is his salary for the week? a. $13,000 b. $350 c. $1520 d. $130

b. $350

Step-by-step explanation:

Let x represent the cost of goods sold by Dave.

We have been given that Dave receives a salary of $200 a week plus a commission of 10% of his weekly sales.

We are asked to write an equation that represents Dave’s weekly earnings in slope-intercept form of equation, where, y-intercept is Dave’s base salary and the slope of the line is his commission.

We know that slope-intercept form of an equation is in format: , where,            

m = Slope of line,

b = The y-intercept.

As we have been given that y-intercept is Dave’s base salary, so this means that value of b is 200.

Now, we need to find the slope of our line.

The slope of line will be Dave's commission. This means that slope of line will be 10% of x.

Upon substituting our given values in slope-intercept form of equation we will get,

Therefore, the equation represents Dave's weekly earnings.

To find Dave's salary we need to substitute in our given equation.

Therefore, Dave's weekly salary for the week is $350 and option 'b' is the correct choice.
