4dr-16r

Remember, the first step in doing this is finding the GCF, or greatest common factor.

Look at both equations, and see what it is.

We see that it is 4.

Look for any variables that are found in both numbers.

r is found in both numbers, so 4r is the GCF.

4dr-16r

What is 4r divided by 4dr? It would be d.

What is -16r divided by 4r? -4

So, our equation now looks like this:

4r(d-4)

So, the last one is correct.

~Hope I helped!~

5.25×4=21

38+21=59

Maya would have enough money to go on the trip.
