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  

Find out the  how many cups of coffee will the shop have sold in 1.75 hours.

To prove

As given

The number of cups of coffee sold at a coffee shop is modeled by y = 48x, where x is the number of hours .

The time it's been open for 1.75 hours .

thus

x = 1.75 hours

put in the equation  y = 48x

Number of coffee cups sold in 1.75 hours = 48 × 1.75

                                                                    = 84 cups

Therefore 84 cups of coffee will be sold by the shop in 1.75 hours.
