Answer 1

Answer: Option B

16.8 minutes

Step-by-step 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

$75t + 50t = 2100$

Now we solve for t

$125t = 2100$

$t = 16.8\ min$

The answer is Option B
