A tanning salon opens with 50 members. Each month the membership increases by 10 members. Write an equation that represents the relationship between the number of months the salon has been opened, x, and the total salon memberships, y?

y= 10x+50

Step-by-step explanation:

x is an increasing variable so, if 10 members are joining each month, x equals 10. 50 is a non increasing number so it has no variable. and y equals all members in total, so y= 10x+50

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side
