To solve this problem, we need to determine the value of x, which represents the initial monthly rent that Jeff agreed to pay.
Let's break down the information given:
Initial monthly rent for the first 3 years: x
Monthly rent for the last 2 years: $350
Total amount paid over 5 years: $19200
We can set up the equation as follows:
Total amount paid for the first 3 years + Total amount paid for the last 2 years = Total amount paid over 5 years
(Initial monthly rent for the first 3 years * 12 months * 3 years) + (Monthly rent for the last 2 years * 12 months * 2 years) = $19200
Let's simplify and solve for x:
(x * 12 * 3) + (350 * 12 * 2) = 19200
(36x) + (8400) = 19200
To isolate x, we subtract 8400 from both sides of the equation:
36x + 8400 - 8400 = 19200 - 8400
36x = 10800
To solve for x, we divide both sides of the equation by 36:
x = 10800 / 36
x = 300
The value of x is 300.
#### 300
The answer is: 300
