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?

84 cups of coffee

Step-by-step 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

you can't solve x because it is 2 linear equation and you only have one equation
