Answer:
64 model cars.
Explanation:
What we know.
Cory has 80 cars in his collection.
That is 25% more than Everett has.
We can deduce that the equation would be c = 1.25e.
So, how do we figure out e?
Well, 1.25 is the same as 5/4.
So, find the reciprocal of 5/4 and multiply by 80.
4/5 * 80 = e
64 = e
