Cormac is making 31 phone calls each week as part of a fundraiser. Last week, he made 8 phone calls on weekdays. Which equation could be used to find x, the number of phone calls he made last week on weekend days? HELPP
Answer: k-y
Step-by-step explanation: Let's call the overall phone calls made every week 'k', and the phone calls made on the weekdays 'y'. Since 'x' is the number of phone calls made per weekend, y+x should equal k. But we don't know what x is so we need to make x the subject, which would be x = k-y.
e.g: k=31, y=8:
31-8= 23 phone calls made on the weekend.
