…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.
