Answer: 20 hours
Explanation:
We can calculate how many cake pops she can make by dividing the rate over the amount of time. This makes our equation 60/4, which means she can make 15 cake pops per hour.
The formula for how much you can make is the rate*time = amount, which means our equation is:
15*t = 300
Dividing both sides by 15, we get:
t = 20, which means Julie will take 20 hours to make 300 cake pops.
