A scale used for a model car is one inch for every 2.5 feet. If the car is originally 7.25 feet long, how long will the model car be?
Set up a proportion. Cross multiply and solve for x.
1 / 2.5 = x / 7.25
2.5x = 7.25
x = 7.25 / 2.5
x = ?

To find out the length of the model car, we need to use the given scale: one inch for every 2.5 feet. We can set up a proportion to solve for the length of the model car:
1 inch / 2.5 feet = x inches / 7.25 feet
First, let's convert 7.25 feet to inches. Since there are 12 inches in a foot, we multiply 7.25 by 12:
7.25 feet * 12 inches/foot = 87 inches
Now we plug in the values into the proportion:
1 inch / 2.5 feet = x inches / 87 inches
To solve for x, we can cross-multiply:
2.5 feet * x inches = 1 inch * 87 inches
Simplifying:
2.5x = 87
Now, we isolate x by dividing both sides of the equation by 2.5:
x = 87 / 2.5
x = 34.8
Therefore, the length of the model car will be approximately 34.8 inches.
