A printer prints 36 photos in 8 minutes. How many minutes does it take to print 45 photos? You can use a ratio table to help you
Readme [11.4K]

Answer:

10 minutes

Step-by-step explanation:

First off, you want to figure out how many photos it prints in one minute. 36 divided by 8 is 4.5. So you should add 4.5 to 36, which makes 40.5 in 9 minutes. Add another 4.5 and you get 45 which you should add another minute. That gives you 10 minutes.

Another way is to find how many per minute which would again be 4.5. 45 divided by 4.5 is 10. So once again, 10 minutes.

3 ft^2 = 3 ft^2 * $5 / ft^2 = 15 dollars
