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.
