kennedy works in a department store selling clothing. she makes a guaranteed salary of $350 per week, but is paid a commission equal to 10% of her total sales for the week. how much would kennedy make in a week if she made x dollars in sales? total earnings when selling $1375: total earnings when selling $x:

Answer

Explanation:

Step1: Identify the formula for total earnings

Total earnings = Base - salary+Commission. The base - salary is $350 and the commission rate is 10% or 0.1 of sales. So the formula for total earnings $y$ when sales is $x$ is $y = 350+0.1x$.

Step2: Calculate total earnings when $x = 1375$

Substitute $x = 1375$ into the formula $y=350 + 0.1x$. Then $y=350+0.1\times1375$. First, calculate the commission part: $0.1\times1375 = 137.5$. Then, calculate the total earnings: $y=350 + 137.5=487.5$.

Step3: General formula for total earnings when sales is $x$

Using the formula $y = 350+0.1x$, when sales is $x$ dollars, the total earnings is $350 + 0.1x$.

Answer:

When selling $1375$ dollars: $487.5$; When selling $x$ dollars: $350 + 0.1x$
