Answer:
Explanation:
To solve this problem, we can set up a system of two equations with two variables. Let x be Justin's base pay for the month and y be the commission rate he receives for each dollar of merchandise sold. Then we have:
400y + x = 384 (equation 1)
700y + x = 447 (equation 2)
To solve for x and y, we can use the method of substitution. Solving equation 1 for x, we get:
x = 384 - 400y
Substituting this expression for x into equation 2, we get:
700y + (384 - 400y) = 447
Simplifying and solving for y, we get:
300y = 63
y = 0.21
Substituting this value of y into equation 1, we can solve for x:
400(0.21) + x = 384
x = 304.80
Therefore, Justin's base pay for the month is $304.80 and he receives a commission of 21% on all merchandise sold.
