Question

A convenience store sells a coffee mug that comes

Answer 1

Answer:

The cost of the mug is of $6.50.

Step-by-step explanation:

The cost of the mug and r refills is given by the following equation:

$C(r) = 2.3r + 6.5$

Cost of the mug:

The cost of the mug is found when no refills are bought, that is, C when $r = 0$, which is $C(0)$

$C(0) = 2.3*0 + 6.5 = 6.5$

The cost of the mug is of $6.50.
