Let's start by finding the amount of money Tom still has to make. TO do this, we can do 120-22 = $98. Let's call the number of weeks x. When we write it as an equation, we get 15x=98. Solving for x, we get x=6.53, but we have to round up to the nearest integer due to the context of the problem. Therefore, the answer is 7 weeks. Hope this helps!
I think the correct answer would be true. The quantity represented by theta is a function of time. This is because the rate of change of angular speed is constant which means the angular distance is changing with time. Hope this answers the question. Have a nice day.
