Question 744041: can I get the expression and define the variables for this word problem:
The cost of gas is 3.35 per gallon. If you travel 40 miles a day and gas mileage is 25 miles per gallon. How much gas money will be spent in a 5 day work week?
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
In terms of units:
( dollars / gallon ) x ( ( miles / day ) / ( miles / gallon ) ) x ( days )
After doing the division, you get:
( dollars / gallon ) x ( miles / day ) x ( gallons / mile ) x ( days )
Now I'll do a slight reordering:
( dollars / gallon ) x ( gallons / mile ) x ( miles / day ) x ( days )
Doing the cancellations, I get:
( dollars / mile ) x ( miles ) = dollars
Which is what you're after
Now, plugging in the numbers:

For a 5 day work week, $26.80 is spent
