A student missed 3 problems on a Physics test and received a grade of 94%. If all the problems were of equal value, how many problems were on the test? Round off your answer to the nearest integer.

my answer is 5 questions

To find the number of problems on the test, we can set up an equation using the information given. Let's assume there were "x" problems on the test.

Since the student missed 3 problems, the number of problems they answered correctly would be x - 3.

The grade of 94% can be represented as 94/100, or 0.94 in decimal form. This indicates that the student correctly answered 94% of the problems.

So, we can set up the equation:
(x - 3) / x = 0.94

Next, we can simplify the equation by multiplying both sides by x:
x - 3 = 0.94x

Now, let's isolate the x variable on one side by subtracting 0.94x from both sides:
0.06x = 3

Finally, divide both sides by 0.06 to solve for x:
x = 3 / 0.06
x ≈ 50

Therefore, there were approximately 50 problems on the test. Rounded to the nearest integer, the answer would be 50.
