Renee notices that her laptop is decreasing in value over time. She paid $1,160 for the laptop, and after 4years, she sees that
it is worth $740. Find a linear function V(t) to model the value of the laptop as a function of t, where t is time in years. Give your answer in the form V(t)=mt+b. Do not use a comma in any numbers.
Using the formula for slope, we can find out that So -105 is the slope, and because she bought her laptop at $1160, the y-intercept is 1160. This means that the equation is V(t)=-105t+1160.
