In a downtown parking lot,there are 5 times as many cars as there are trucks. There are 12 trucks in the parking lot.
Write an equation that shows the number of cars parked in the parking lot.
How many cars are in the parking lot
well start by representing your trucks and cars as variables
we'll use x for trucks since you are using them to figure out the number of cars and y for the number of cars so...
x= # of trucks
y= # of cars
now how are they related? well, there are 5 times as many cars as trucks, so that means you multiply whatever value of trucks you have by 5?
How would you represent that algebraically using the variables we have assigned above?
