What is the cost of labor per square if two workers installed 10 squares of material in 8 hours and are paid $25 and $15 per hour?

To determine the cost of labor per square, we first need to calculate the total wages paid to the workers and then divide that total by the number of squares they installed.

The two workers are paid $25 and $15 per hour. Over the course of 8 hours, the calculations for each worker's total wages are as follows:

1. The first worker’s total earnings: ( 8 , \text{hours} \times 25 , \text{dollars/hour} = 200 , \text{dollars} )

2. The second worker’s total earnings: ( 8 , \text{hours} \times 15 , \text{dollars/hour} = 120 , \text{dollars} )

Now, summing these amounts gives us the total labor cost for the installation:

[ 200 , \text{dollars} + 120 , \text{dollars} = 320 , \text{dollars} ]

Next, to find the labor cost per square, we divide the total labor cost by the number of squares installed:

[ \frac{320 , \text{dollars}}{
