andre

Step-by-step explanation:

he would have 120 bucks and elena would have 90

Andre has more money in his savings account than Elena.

Step-by-step explanation:

Andre: f(x) = 100 + 5x

Elena: f(y) = 10 + 20x

solve each for 4

f(4) = 100 + 5(4)

f(4) = 100 + 20

f(4) = 120

Andre has $120 after 4 weeks.

f(4) = 10 + 20(4)

f(4) = 10 + 80

f(4) = 90

Elena has $90 after 4 weeks.
