18p-45=0 whats the answer?

p=2.5

Step-by-step explanation:

First, you would do the inverse operation by adding 45 to both sides to get 18p by itself. By adding 45 to both sides the -45 and 45 would cancel out and there will be a 45 on the right side of the equation. 18p=45   Next, you would have to divide by 18 on both sides of the equation. So 18/18 equals 1 so you would only have p left and 45/18 is 2.5 which leaves you with p=2.5

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