Camden drove 320 miles in 8 hours. If he continued at the same rate, how far would he travel in 7 hours?

280 miles

Step-by-step explanation:

We want to determine what speed Camden is going first so we can find the distance. To do so, you can divide the total miles (320) by the number of hours (8) to find he is driving 40 miles per hour. Then, you can take that and multiple it by the number of hours he will drive (7) to get 280 miles. I hope this helps! :)

Here are the equations:
63 + 12n =
and
15n =

So we need to figure out when they will meet up at the same value...

63 + 12( )=
and
15 x ( )=

So for this, the starting fee is $63 ahead of the one without the starting fee.

So we find the multiple where each equals the same value...

63 + 12(21)= 315
and
15(21)= 315

12 x 21 = 252
252 + 63 = 315

15 x 21 = 315

So after 21 classes, the cost will be the same.

Hope this helped! :)
