This question might blow the shmoopee right off your head…

00:06

John just moved his entire family into a shoe.

00:09

The old lady who lived there before is renting it to him at a really reasonable rates.

00:13

If x is the total amount John paid for y number

00:16

of months of rent, including a one-time security deposit in the amount of z dollars…

00:21

…which of the following expressions tells how much he spends on rent per month?

00:26

And here are the potential answers...

00:30

OK, so this question is asking for an expression for how much John spends on rent per month.

00:36

Since we're not given any actual money values, we can use variables.

00:40

So to find rent spent per month, we have to find the

00:44

total rent spent divided by number of months, or y.

00:48

Since we know x is the total amount of money on housing John spent, and z is the security deposit…

00:55

…we can find total rent spent but just taking x minus z.

01:00

So rent spent per month is total rent spent, or x minus z over y, number of months.

01:07

So the answer is B. That's it. Bye.
