An average American child aged 0-2 years old has about 915 minutes of screen time in 5 days. 6 times the difference between a child aged 0-2 years (915) and a child aged 3-5 years (X) is the same as the sum of 100 and a child aged 3-5 years (X). How much screen time does an average child (x) have?

For children ages 2 to 5, limit screen time to one hour a day of high-quality programming. As your child grows, a one-size-fits-all approach doesn't work as well. You'll need to decide how much media to let your child use each day and what's appropriate.

Step-by-step explanation:

For kids aged 2 to 5, screen time should be limited to 1 hour per day, and parents should watch the programs with their child. Also, parents should have times when screens are turned off, and bedrooms should be media-free.

47 - 90 = 43

43 - 180 = x

x = 137
