Carly is ordering calendars online each calendar costs $12 with a one time shipping fee of $15 which equation can be used to find the total cost t of ordering n calendars

12n + 15 = t

Step-by-step explanation:

Each calendar costs $12. We don't know how many calendars Carly is ordering but we know that n represents the calendars so we have 12n.

We also know that there is a $15 shipping fee which will not change at all so now we have 12n + 15.

We know that t is the total so the equation to find the total cost of ordering n calendars is : 12n + 15 = t
