Re: Exponents Word Problem

Hi there, was that the whole question?

Re: Exponents Word Problem

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

Re: Exponents Word Problem

Should I derive the equation to find maximum then?

Re: Exponents Word Problem

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

Re: Exponents Word Problem

ohhhhh!

ok :D thanks so much I got it from here!

Re: Exponents Word Problem

t= 24 ... highest achieved will be a 98

t=0 .... lowest/ without studying will be 65 thanks!
