−12 ÷ 4 expression best shows the temperature change each hour. Hence Option C is correct
<u>Solution:</u>
Given that, the temperature has been going down at a constant rate.
In 4 hours it went down by 12 degrees.
Now, we have to choose the correct option which best describes about the change in temperature for each hour.
Now, we know that, 12 degrees decreased in 4 hours.
Then, number of degrees decreased in one hour =
Number of degrees changed in one hour =
Because the temperature is decreasing we have to add a (-) symbol before the change in degrees.
So, now, <em>number of degrees changed in 1 hour </em>=

It is given that:
Monthly Rent = A
Total Money Paid to Landlord = Y
The landlord requires initial payment to include:
- 1st month's rent
month's rent or 50% of monthly rent for Security Deposit
- 40% of monthly rent for utility bills
- 5% of monthly rent for health club
- 13% of monthly rent per person for other services
Also, Total Amount Paid to the Landlord = $2574
Number of People Sharing the Apartment = 3
Basis the above information,
Y = (100% * A) + (50% * A) + (40% * A) + (5% * A) + (13% * A * 3)
⇒ Y = A + (0.5 * A) + (0.4 * A) + (0.05 * A) + (0.39 * A)
⇒ Y = A + (0.5 * A) + (0.4 * A) + (0.05 * A) + (0.39 * A)
⇒ Y = 2.34 * A
Substituting the value of Y to determine A
⇒ 2,574 = 2.34 * A
⇒ A = 1,100
Hence, the monthly rent is $1,100
