Answer:

7 minutes

Step-by-step explanation:

Given the expression for time

[tex]t =2n-3[/tex]

say a customer buys 5 coffees, hence n=5

substituting n=5 into the function time it takes to prepare a coffee we have the time it will take to prepare 5 coffees

[tex]t= 2(5)-3\\t=10-3\\t=7[/tex]

Hence it will take 7 minutes to prepare 5 coffees
