Respuesta :

Let x be the total number of questions. We know that Jess answered correctly 35 of them, and those 35 are the 74.47% of all questions.

So, can build the proportion linking the correct answers to the total number of questions:

[tex]35\div x = 74.47\div 100[/tex]

Solving for x, we have

[tex]x = \dfrac{3500}{74.47}\approx 47[/tex]

Answer:

There were 47 questions in the test.

Step-by-step explanation:

All the questions in the test = 100%.

74.47% is equivalent to 35 questions, so:

100% = 100 / 74.47 * 35

=  47 (answer).
