Thread: Exponents Word Problem

represent the expected score for a student who studies hours for a test. Suppose and test scores must be integers.

Would you solve this like an absolute value equation and have one positive and one negative equation, or no? How should I start. I plugged in k. How can I find the two values?

Hi there, was that the whole question?

Oh. I'm sorry!
Basically they want us to find the lowest/highest test scores.

Here is the remainder of the problem.
What is the highest score the student can expect?

If the student does not study, what score can he expect?

Find the maximum of the equation for t>0, plot the equation to find the value by inspection or use some calculus.

substitute t=0 into the equation

Should I derive the equation to find maximum then?

I found the maximum by looking at the equation, what is the range of for ?

ohhhhh!
ok thanks so much I got it from here!

t= 24 ... highest achieved will be a 98
t=0 .... lowest/ without studying will be 65 thanks!

Nice work!
