Question

The amount of time (t) in minutes it takes to make a coffee at Starbucks is related to (n) the number of coffees they purchase.the equation is t=2n-3. How long does it take if a customer buys 5 coffees?

13 minutes
7 minutes
4 minutes
None of these choices are correct

Answer 1

Are you sure it’s not 7 minuets. Because it seems right to me.

t=2(5)-3
t= 10-3
t=7

Check:

7= 10 -3
7=7
Therefore it’s correct.

I even looked at another website where they had the same question thing and it said it was 7 minuets also so I’m not sure if ur computer is messed up or I’m dumb.
