Question

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?

Answer 1

Okay, lets take a look at this.

So we start of with the constant of 20 minutes.

She increases it 5min/week.

We can form an equation which is 45=5x+20. We can easily solve this by subtracting 20 from both sides and dividing both sides by five, ending in 5 as the answer.

Answer: 5 weeks

Answer 2

She can increase her exercise for 5 week
