I had to answer a question similar to that one on Math XL. This question was about renting a truck instead of needing a 48 mile taxi. (Took me a long time just to find the truck question, but I am giving you the truck help me answer the question, in hopes that it will help you.)
The cost of renting a truck from Hamilton Auto Rental is $47.60 per day plus $0.15 per mile. The expression 47.60 plus 0.15 m represents the cost of renting a truck for one day and driving it m miles. Evaluate 47.60 plus 0.15 m for m equals 120.
Substitute the numerical value for each variable into the expression and simplify the result.
I am sorry if that didn't help you, but it was the closest thing I could find to use to help you.
<span>Jack Watkins earns a base salary of $1500 a month, plus a 4% commission on the sales he makes. What is his gross pay of his sales for the month are $8000.
solution:
Gross pay=(salary)+(commissions)
base salary=$1500
commission=4%
monthly sales=$8000
commissions earned in cash
=4/100</span>×8000
=$320
thus
Gross salary=320+1500=$1820
You are adding two each time
