Answer:

Andre

Step-by-step explanation:

This situation can be modeled with the equations:

A = 100 + 5w

E = 10 + 20w

Let w represent the number of weeks that have passed since they have started saving money. Andre(A) has saved $5 per week and Elena(E) has saved $20 per week. Substituting 4 into the equation (because 4 is the number of weeks that have passed so far) and evaluating we come to the realization that Andre still has more money than Elena because he now has $120 and Elena has $90.

Step-by-step explanation:

You can solve systems of equations using either substitution or elimination.  For these problems, I recommend elimination.  I'll do the first one as an example.

-3x + 16y = 9

-4x + 8y = 12

Multiply the second equation by -2.

8x − 16y = -24

Add to the first equation (notice the y's cancel out).

(-3x + 16y) + (8x − 16y) = 9 − 24

5x = -15

Solve for x.

x = -3

Now you can plug this into either equation to find y.

-3(-3) + 16y = 9

9 + 16y = 9

y = 0

The solution is (-3, 0).

If you use the first answer, the equation becomes 2x + 2y = 16.  You could subtract this from equation Q to eliminate x.

The second answer makes equation P -2x - 2y = -16.  You could add this to equation Q to eliminate x.  You can use both of these methods to eliminate the x term, but if you can only choose one, you should choose the second option.
