Answer:
56 problems
Step-by-step explanation:
So we already know that the answer is: 56. However, a good help is knowing how to obtain this answer from the data provided.
Tony's quiz had 80 questions
Tony correctly answered 70% of them.
We can always write a percentage amount as a ratio by dividing the amount by 100.
.
This means that for every 100 questions, tony will respond correctly 70.
So, if Toni did a questionnaire of n questions, the amount that will answer correctly is calculated by the following expression:
![C = n*\frac{70}{100}](https://tex.z-dn.net/?f=C%20%3D%20n%2A%5Cfrac%7B70%7D%7B100%7D)
If
then:
![C = 80 * \frac{70}{100}\\\\C = 56](https://tex.z-dn.net/?f=C%20%3D%2080%20%2A%20%5Cfrac%7B70%7D%7B100%7D%5C%5C%5C%5CC%20%3D%2056)
