mike earns $6.50 per hour plus 4% of his sales. enter an equation for mike’s total earnings, e, when he works x hours and has a total of y sales, in dollars.
Answer
Explanation:
Step1: Calculate hourly - earnings
Hourly rate is $6.50 and he works $x$ hours, so hourly - earnings are $6.50x$. $6.50x$
Step2: Calculate sales - commission
He gets 4% (or 0.04 in decimal form) of his sales $y$. So sales - commission is $0.04y$. $0.04y$
Step3: Find total earnings
Total earnings $E$ is the sum of hourly - earnings and sales - commission. $E = 6.50x+0.04y$
Answer:
$E = 6.50x + 0.04y$
