Mr. Holopirek is a very well dressed person. He currently owns 20 pairs of basketball shorts and he buys 3 pairs every month. Write an equation to model the relationship between shorts Mr. Holopirek owns and months that have passed.

y=3x+20

Step-by-step explanation:

y represents the total shorts Mr. Holopirek owns.

x represents the number of months that have passed.

The 20 pairs of basketball shorts he already owns is a constant, so you don't need a variable next to it, but you still need it in the equation.
