Suppose that the number of cars manufactured at an automobile plant varies jointly as the number of workers and the time they work. If 85 workers can produce 136 cars in 8 hours, find the number of cars that 125 workers can produce in 7 hours.

Answer :

125 workers can produce approximately 102.94 cars in 7 hours.Additionally, this assumes that the constant of Proportionality remains the same for different numbers of workers and hours worked.

We are given that the number of cars manufactured at an automobile plant varies jointly as the number of workers and the time they work. This can be expressed as:

C = kWT

where C is the number of cars produced, W is the number of workers, T is the time they work, and k is a constant of proportionality

We can use this formula to solve the problem. We are given that 85 workers can produce 136 cars in 8 hours, so we can set up an equation using this information:

136 = k(85)(8)

Solving for k, we get:

k = 2/17

Now we can use the formula to find the number of cars that 125 workers can produce in 7 hours:

C = (2/17)(125)(7)

C = 102.94

Therefore, 125 workers can produce approximately 102.94 cars in 7 hours.

It's important to note that this is an approximation since we have rounded the answer to two decimal places. Additionally, this assumes that the constant of proportionality remains the same for different numbers of workers and hours worked.
