Question

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.

Answer 1

Answer:

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
