Michael and his wife are each starting a saving plan. Michael will initially set aside $75 and then add $50.85 every week to the
savings. The amount A (in dollars) saved this way is given by the function =A+7550.85N, where N is the number of weeks he has been saving. His wife will not set an initial amount aside but will add $65.95 to the savings every week. The amount B (in dollars) saved using this plan is given by the function =B65.95N.
Let T be total amount (in dollars) saved using both plans combined. Write an equation relating T to N. Simplify your answer as much as possible.
Okay. To find the distance apart from each other, subtract 15.3 and 7.5. When you do that, you should get 7.8. -7.5 and -15.3 are 7.8 units away on a number line.
