Question 1175867: Are these correct? I want to check my answers.
Lewis is saving for a down payment of $8,750 on a house. The initial amount of money he has saved is $250, and the amount of money he plans on saving every month is $340. To model the situation, he created this equation, where x represents the number of months and y represents the total amount of savings:
y = 250 + 340x.

You can put this solution on YOUR website!
you start with y = 250 + 340x
you're good until:
(y - 250) / 340 = x
your last step in the table isn't correct.
it should be:
(8750 - 250) / 340 = x
that's because you replaced y with 8750 that it is equal to.
that step would be called substitution.
you then perform the simplification to get:
25 = x
that's your solution.
