The resale value of a textbook decreases by 25% with each previous owner. A new textbook is sold for $85. Which function represents the resale value of the textbook after x owners?
Answers
Since the value decreases by 25% each time, the next cost is the current cost times 0.75 (since new cost is 75% of current cost). To find the value of the book after x times sold, you can use:
Just plug in the number of times it is resold to find the value.
A exponential function would represent it nicely f(x)=b*a^x Reason being a decrease of % a = 1+r r = -25% = -0.25 And b being what the original cost of the book f(x)=85*0.75^x Where f(x) is the price after x amount of previous owners

4(x+1)-ax=x+5 solve for x
Answers
4(x + 1) - ax = x + 5 4(x) + 4(1) - ax = x + 5 4x + 4 - ax = x + 5 - x - x 3x + 4 - ax = 5 - 4 - 4 3x - ax = 1 x(3) - x(a) = 1 x(3 - a) = 1 3 - a 3 - a x = 1/(3 - a)
