Question

The number of cups of coffee sold at a coffee shop is modeled by y = 48x, where x is the number of hours since the shop opened. How many cups of coffee will the shop have sold by the time it's been open for 1.75 hours?

Answer 1

84 cups of coffee

Explanation:

All you have to do is plug in for x. So because you know that x is the number of hours, you just have to take your hours, 1.75, and put in place of x.

y = 48(1.75)

now multiply 48 by 1.75 and you get 84.

hope this helps
