Lexi and maria had $250 altogether. after lexi spent 2/5 of her money and maria spent $40 they had the same amount of money left. how much more money did lexi have in the beginning.

The amount of money that Lexi had at the beginning was $131.25

Step-by-step explanation:

Let

x > amount of money that Lexi had at the beginning

y > amount of money that Maria had at the beginning

we know that

x+y=250 > equation A

(1-2/5)x=y-40

(3/5)x=y-40

y=(3/5)x+40 > equation B

substitute equation B in equation A and solve for x

x+(3/5)x+40=250

(8/5)x=250-40

(8/5)x=210

x=210*5/8

x=$131.25

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
