Steps/Work
Now, there are 15 smokers (15% of 60) and 60-15=45 non-smokers at a party. We need there to be 30 cheese and 30 pepperoni pizzas, in this case there will be 50% cheese and 50% pepperoni.
Therefore 45-30=15 cheese must be changed to pepperoni pizza.
Answer: D.
Therefore 45-30=15 cheese must be changed to pepperoni pizza.
