What is an equation that relates the grade earned on a test, g, with the amount of time spent studying, t. in hours?

Respuesta :

It is given that,

A student spends 5 hours studying and makes a grade of 89 on the test.

To write an equation that relates the grade earned on a test in t hours.

Let us take,

For 5 hours, the grade is 89

For 1 hour, the grade will be,

[tex]\frac{89}{5}=17.8[/tex]

Then for t hours, the general equation will be,

[tex]g=17.8t[/tex]

Hence, the answer is g=17.8t.
