The function j(x)=39x is the number of jumping jacks you can do in x minutes how many can you do in 5 minutes'?

This is asking you to evaluate the function when x is 5...so all you do here is substitute 5 for x and simplify.. since the question defines "x" as the number of minutes...and j(x) represents the number of jumping jacks.

j(x) = 39x

j(5) = 39(5)

j(5) = 195 <--- answer...

So you do 195 jumping jacks in 5 minutes

I really hope this helps :)
