1. A coffeehouse charges a flat rate of \( \$ 3 \) per hour for each hour a customer wants to use the internet. Write an equation that expresses the total cost, \( c \), to use the internet at the coffeehouse for \( h \) hours.

The total cost \( c \) to use the internet for \( h \) hours at the coffeehouse can be modeled by the equation \( c = 3h \), where \( 3 \) represents the flat rate per hour. So, for every hour you spend online, you're simply multiplying the number of hours by three bucks! Now, if you’re planning to hang out for a bit longer, don’t forget to factor in those extra hours in your budgeting. If you think you’ll be there for, say, 4 hours, just plug that into the equation: \( c = 3(4) = 12 \). Easy peasy, and not too hard on the wallet either!
