Lamar and his wife are each starting a saving plan. Lamar will initially set aside
[FONT=&quot]$[/FONT][FONT=&quot]75[/FONT]


and then add [FONT=&quot]$[/FONT][FONT=&quot]40.75[/FONT]


every week to the savings. The amount [FONT=&quot]A[/FONT]


(in dollars) saved this way is given by the function [FONT=&quot]=[/FONT][FONT=&quot]A[/FONT][FONT=&quot]+[/FONT][FONT=&quot]75[/FONT][FONT=&quot]40.75[/FONT][FONT=&quot]N[/FONT]


, where [FONT=&quot]N[/FONT]


is the number of weeks he has been saving.His wife will not set an initial amount aside but will add
[FONT=&quot]$[/FONT][FONT=&quot]75.65[/FONT]


to the savings every week. The amount [FONT=&quot]B[/FONT]


(in dollars) saved using this plan is given by the function [FONT=&quot]=[/FONT][FONT=&quot]B[/FONT][FONT=&quot]75.65[/FONT][FONT=&quot]N[/FONT]


.Let [FONT=&quot]T[/FONT]


be total amount (in dollars) saved using both plans combined. Write an equation relating [FONT=&quot]T[/FONT]


to [FONT=&quot]N[/FONT]


. Simplify your answer as much as possible.

[FONT=&quot]T=[/FONT]
 
Lamar and his wife are each starting a saving plan. Lamar will initially set aside $75 and then add $40.75 every week to the savings. The amount A (in dollars) saved this way is given by the function =A+7540.75N , where N is the number of weeks he has been saving.His wife will not set an initial amount aside but will add $75.65 to the savings every week. The amount B (in dollars) saved using this plan is given by the function =B75.65N .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.

T=

See red above.
Before you can even attempt to do such a problem or do ANY calculus you better learn what a function is. What happened in Basic Algebra, College Algebra, Trigonometry and Precalculus--you never learned in any of those courses what a function is?
