You and a partner tend 3 machines that run continuously. One prints 200 plastic bottles per hour, one prints 180 plastic bottles per hour, and one prints 150 plastic bottles per hour. If the machines work at their average rates, how many plastic bottles will they print during the 8.5 hours you are at the factory for your shift?

A. 530
B. 538.5
C. 1,700
D. 4,240
E. 4,505



Answer :

Let's break down the problem step-by-step:

1. Identify the production rates of each machine:
- Machine 1: 200 plastic bottles per hour
- Machine 2: 18 plastic bottles per hour
- Machine 3: 150 plastic bottles per hour

2. Determine the duration of the shift:
- The shift lasts for 8.5 hours.

3. Calculate the total number of plastic bottles produced by each machine during the shift:
- Machine 1:
[tex]\[ \text{Production by Machine 1} = 200 \, \text{bottles/hour} \times 8.5 \, \text{hours} = 1700 \, \text{bottles} \][/tex]
- Machine 2:
[tex]\[ \text{Production by Machine 2} = 18 \, \text{bottles/hour} \times 8.5 \, \text{hours} = 153 \, \text{bottles} \][/tex]
- Machine 3:
[tex]\[ \text{Production by Machine 3} = 150 \, \text{bottles/hour} \times 8.5 \, \text{hours} = 1275 \, \text{bottles} \][/tex]

4. Calculate the total production from all machines combined during the shift:
[tex]\[ \text{Total Production} = 1700 \, \text{bottles} + 153 \, \text{bottles} + 1275 \, \text{bottles} = 3128 \, \text{bottles} \][/tex]

5. Compare the total production to the given answer choices:
A. 530
B. 538.5
C. 1,700
D. 4,240
E. 4,505

The correct answer is not listed among the provided options since the total production during the 8.5 hours shift is 3128 plastic bottles. Hence, none of these options (A to E) are correct.
