Step-by-step explanation:
Answer:
11 months
788 disc
Step-by-step explanation:
Let
x = number of months
Fry's Electronics;
= 920 - 12x
Blu-ray discs:
= 502 + 26x
Equate both equations
920 - 12x = 502 + 26x
920 - 502 = 26x + 12x
418 = 38x
x = 418/38
x = 11 months
number of months = 11
Substitute 11 into any of the equation
Fry's Electronics;
= 920 - 12x
= 920 - 12(11)
= 920 - 132
= 788 disc sold in that months
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.
