The Crayola crayon company can make 2400 crayons in 4 minutes. How many crayons can they make in 15 minutes? Solve this problem
densk [106]
So, The Crayola Crayon company can make 2400 crayons in 4 minutes. In other words, every 4 minutes they can make 2400 crayons, right? So, in 15 minutes how many would they have made? Well, what we do is we divide 15 by 4 which is 3.75. Then we multiply the result, 3.75, by 2400. 3.75 * 9000. So, in 15 minutes, Crayola  would have made 900 crayons!

4/2400 = 15/x

Step 1: Cross Multiply

4/2400 = 15/x

4 * x = (15) * (2400)

4x = 36000

Step 2: Divide both sides by 2

4x/4 = 36000/2

x = 9000

The answer is, 9000!!! :D
