To find the percentage of cookies baked by Jenny we first have to know how many cookies total there were. 15+18+17=50 cookies all together. The question is asking us "what percentage" (x) "of" (multiply) 50 "is" (equals) 15? Using the variables and numbers only our questiion becomes 50x = 15. Divide both sides by 50 to get x = .3. Since this value is a percentage, we find that percentage by multiplying by 100. 30%.
