So for this there is going to be two equations; One showing how much they earned total and one showing how much more Garth made.
Let x mean how much Sandi made and y mean how much Garth made.
The first equation is going to be
The second equation is going to be
.
I'll be using the substitution method since that is already set up for it. So in the first equation substitute y for x+25 since the second equation tells us that is the equivalent to y.
And your equation should look like this:
. From here you can solve for x.
Combine like terms to get
Subtract 25 on each side to get
Divide 2 on each side to get
Now that we had got what Sandi had earned, we can substitute x for 200 in either equation to solve for y. I'll be solving for y in the second equation.
To sum it up, Sandi earned $200 and Garth earned $225.
