A survey of teens showed that teens in brooklyn, ny aged 13-18 spend 16.9 hours per week online. Teens in charlotte, nc spend 13.2 hours per week online. Write and solve an addition equation to find the difference on time spent online by teens in these cities
To work this out we have to do 16.9 hours - 13.2 hours = 3.7 hours so there is a 13.7hour difference and to show it as an addition equation you do 13.2 hours + 3.7hours = 16.9 hours
