Question

parker correctly answered 70% of the questions on his math test. If he answered 35 questions correctly, how many questions were on his math test? define a variable. write and solve an equation

Answer 1

70% of the total questions = 35

0.70x = 35.....with x being the total questions
x = 35 / 0.70
x = 50 <== 50 total questions

Answer 2

Let the total number of questions in the math test be defined by the variable x.

Now, we know that Parker correctly answered 35 questions. These 35 questions make 70% of the total number of questions on his math test.

The information we have above can be expressed as an equation given below:

70% of x=35

This can be rewritten as:

`(70)/(100)x=35`

Thus, to find the total number of questions we will have to isolate x.

`\therefore x=(35* 100)/(70)=50`

Therefore, there were a total of 50 questions in the math test.
