Melissa exercises for 20 minutes every day. she decides to increase her daily exercise time by 5 minutes each week. however, according to her doctor’s orders, she can spend no more than 45 minutes a day exercising. for how many weeks can melissa increase her exercise time this way?

Let's start by finding the difference between Melissa's maximum time limit and her every day exercising time.

45-20 = 25 minutes.

Now we know that each week she increases her time by 5 minutes. Therefore, we have to find how many 5's can fit in the 25 minute difference.

25/5 = 5 weeks

Melissa increases 5 minutes every week for 5 weeks until she reaches her limit of 45 minutes.

I hope that helps!
