Question

Write an equation for the following situation:

Answer 1

Let
x---------> represent the number of weeks
y---------> represent the amount of money saved

we know that
for x=6 weeks    y=40*6-------> $240
then 
300-240--------> $60----------> initial amount for x=0

the equation is 
y=40*x+60

the answer is
y=40*x+60
