The largest room in Mrs. McAvoy's house is 45 feet wide and 30 feet long. The smallest room in that same house is 15 feet wide and 8 feet long. What is the difference in area between the largest room and the smallest room?
The area of the largest room is 45 ft x 30 ft = <<45*30=1350>>1350 sq ft
The area of the smallest room is 15 ft x 8 ft = <<15*8=120>>120 sq ft
The difference between the two is 1350 sq ft - 120 sq ft = <<1350-120=1230>>1230 sq ft

Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
You are solving math problems. Here are some examples of how to solve the task:

Ryan is looking for people to crowdfund his new business idea.  If the average person funds $10 to a project they're interested in, how many people will Ryan have to recruit to fund a $1,000 business if he has $200 already?First, we need to determine how much money Ryan needs to hit his goal which we find by subtracting his available cash from his target, performing 1000-200=<<1000-200=800>>800 dollars needed.
Since the average person contributes $10 when crowdfunding, this means he needs to find 800/10=<<800/10=80>>80 people to fund his business well enough for him to hit his goal.

Mark is filling a punch bowl that can hold 16 gallons of punch. He fills it part way, then his cousin comes along and drinks half the punch in the bowl. Mark starts to refill the bowl and adds 4 more gallons, but then his friend Sally comes in and drinks 2 more gallons of punch. After that, Mark has to add 12 gallons of punch to completely fill the bowl. How much punch did Mark initially add to the bowl?First, figure out how much punch was left in the bowl before Mark refilled it by subtracting the 12 gallons he added from the bowl's total capacity: 16 - 12 = <<16-12=4>>4 gallons
Next, figure out how much punch was in the bowl before Sally came along: 4 + 2 = <<4+2=6>>6 gallons.
Next, figure out how much punch was in the bowl before Mark started to refill it: 6 - 4 = <<6-4=2>>2 gallons
Finally, multiply that amount by 2 to find out how much punch there was before the cousin drank half: 2 * 2 = <<4=4>>4 gallons

Now, solve this next question in the style of the above examples:

The largest room in Mrs. McAvoy's house is 45 feet wide and 30 feet long. The smallest room in that same house is 15 feet wide and 8 feet long. What is the difference in area between the largest room and the smallest room?

### Response:
The area of the largest room is 45 ft x 30 ft = <<45*30=1350>>1350 sq ft
The area of the smallest room is 15 ft x 8 ft = <<15*8=120>>120 sq ft
The difference between the two is 1350 sq ft - 120 sq ft = <<1350-120=1230>>1230 sq ft
