Answer: Option B
16.8 minutes
Explanation:
Machine A produces 75 fishing lures per minute.
Machine B produces 50 fishing lures per minute.
Let's call t time in minutes.
So we want to know how long it will take to produce 2100 fishing lures
We propose the following equation
![75t + 50t = 2100](https://img.qammunity.org/2020/formulas/mathematics/middle-school/u63c377477rmvnt63wq8arnbg323awmpzl.png)
Now we solve for t
![125t = 2100](https://img.qammunity.org/2020/formulas/mathematics/middle-school/a87vuw7phod4n8hy5f7y6b29li599pby62.png)
![t = 16.8\ min](https://img.qammunity.org/2020/formulas/mathematics/middle-school/eclflariu3ap7hnvxxkuj41yfzwu2ixpza.png)
The answer is Option B
