Gina is comparing the membership fees for two museums. The art museum charges a one-time fee of $7.25 plus $3.50 per month. - Th

Answer:

<em>here two links for your answer. https://quizlet.com/325167814/financial-math-flash-cards/ https://quizlet.com/475135130/financial-math-e2020-flash-cards $2.5</em>

<em></em>

<em>Step-by-step explanation:</em>

<em></em>

<em>The art museum charges a one-time fee of $8.25 plus $2.25 per month.</em>

<em></em>

<em>So, the cost function for membership for x months in the art museum f(x) = 8.25 + 2.25x .............. (1)</em>

<em></em>

<em>Again, the science museum charges a one-time fee of $10.75 plus $3.5 per month.</em>

<em></em>

<em>Hence, the cost function for membership for x months in the science museum g(x) = 10.75 + 3.5x ........... (2)</em>

<em></em>

<em>So, from both the equations it is clear that for only joining the monthly charges are zero.</em>

<em></em>

<em>So, f(0) = 8.25 and g(0) = 10.75.</em>

<em></em>

<em>Therefore, Barrett will save by joining the art museum instead of the science museum by $(10.75 - 8.25) = $2.5. (Answer)</em>
