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.
