A house purchased for $125,000 is expected to appreciate according to the formula y = 7,500x + 125,000, where y is the value of the house after x years. Find the value of the house 5 years later.

what did U get when U plugged 5 in for x?

Confused about what did U get when U plugged 5 in for x?

You were given a formula for the value of y when given a value of x. You were given a value for x, and asked for the corresponding value of y. You showed no work. The previous poster asked regarding the value you had obtained for y when you plugged the given value for x into the given formula for y.

Where, exactly, are you getting confused?

do U know wat variables are?
do U know wat plug & chug means?
have U taken algebra at all?

I'm taking algebra right now.

The variables are letters. Example: x and y

So is it y = 7,500(5) + 125,000

So is the answer: 162500

I think the other poster was asking if YOU know what variables are. They teach about varioables in algebra classes. They can't get to "formulas" w/o doing variables and evaluation first. So you not knowing how to plug numbers they give you into formulas they give you makes it sound like you've never done algebr ayet.

So is it y = 7,500(5) + 125,000
So is the answer: 162500

That's what I get.
