Aschool is repainting some of its classrooms. each classroom is repainted with 5.5 gallons of paint. write and solve an equation to determine the gallons of paint the school must purchase if they repaint 18 classrooms.

idk how to write the equation

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?

Ican’t sorry i would if i could
