Question

Pedro has $1500 in his savings account. He plans to
withdraw $75 each week. Maria has a savings account
with $1200. She plans to withdraw $50 each week. In
how many weeks will the accounts be equal?

Answer 1

Answer:

about 4 weeks

Step-by-step explanation

pedro: y = 1500 - 75x

Maria: y = 1200 - 50x

put y's equal to each other

1500-75x=1200-50x

-1200             -1200

300-75x=50x

+75x          +75x

300 = 125x

/125       /125

x=3.78787878788

so about 4 weeks
