A popular online shaving club charges a $12 per month fee plus $1.50 per safety razor you purchase. Write an equation for the cost (y) based on the number of razors (x) you purchased
y=12x+1.50 every month they charge $12 dollars and for the first sign up there is a sign up fee basically or a safety fee. Once you have a certain number of months you plug that in for x solve it and then you find your Y.
