Answer:

c = P-25

Step-by-step explanation:

Given the formula P = c+m which is used to determine price P of an  item that costs c cents and a markup of m cents. To get the value of c, we will make c the subject of the formula;

P = c+m

subtract m from both sides

P-m = c+m-m

P-m = c

c = P-m

Given the price of mark up on a can of juice to be 25 cents, we will substitute m = 25 into the resulting expression as shown;

c = P-25

Hence the equivalent version of this  formula solved for c is c = P-25
