For the most part you have to follow these rules in order to get the correct answer. For this question you first have to multiply 19 by 4 to get 76. Next you add 35 to the number. The sum of 76 and 35 is 111. You final step is to subtract 21. Your final answer is 90. I hope this helps!
20 percent the ratio is 16 over 80 multiplied by 100 over 1
We're looking for such that
Multiplying both sides by gives us
Notice that when , the term involving vanishes and we're left with
Then
so that
