A car dealership has both
new and used vehicles on
their lot. Currently, they
have 280 vehicles. The
ratio of new to used
vehicles is 7:3. How many
vehicles are new?

The number of new vehicles is 196

Step-by-step explanation:

Let

x ----> the number of new vehicles

y ----> the number of used vehicles

we know that

Currently, they  have 280 vehicles

so

----> equation A

The  ratio of new to used  vehicles is 7:3

so

----> equation B

substitute equation B in equation A

solve for y

Find the value of x

therefore

The number of new vehicles is 196
