Let's solve the problem step-by-step:
1. Determine the production rate of each machine:
- Model A produces 300 parts per hour.
- Model B produces 450 parts per hour.
2. Find out how many of each machine the company has:
- The company has 3 Model A machines.
- The company has 1 Model B machine.
3. Calculate the total number of parts produced by all Model A machines in one hour:
- Each Model A machine produces 300 parts per hour.
- With 3 Model A machines, the total production is:
[tex]\[
300 \, \text{parts/hour} \times 3 \, \text{machines} = 900 \, \text{parts/hour}
\][/tex]
4. Calculate the total number of parts produced by the Model B machine in one hour:
- The Model B machine produces 450 parts per hour.
- With 1 Model B machine, the total production is:
[tex]\[
450 \, \text{parts/hour} \times 1 \, \text{machine} = 450 \, \text{parts/hour}
\][/tex]
5. Add the total parts produced by Model A machines and Model B machine to get the company's total production in one hour:
[tex]\[
900 \, \text{parts/hour} + 450 \, \text{parts/hour} = 1350 \, \text{parts/hour}
\][/tex]
Therefore, the company can produce 1,350 parts in one hour. The correct answer is:
1,350
