Answer: e= 6.50x + y 0.04
Explanation:
Hi, to answer this question we have to multiply the number of hours he works (x) by the earnings per hour ($6.50), add the product of the total sales (y) and the percent of sales he gets in decimal form (0.04 = 4/100).
That expression must be equal to the total earnings (e)
Mathematically speaking:
e= 6.50x + y 0.04
