The weekly demand for cortisone cream at a major drug store chain in Spokane is 135 units at a price of $3.50 each. If the price is increased to $3.95, the weekly demand falls to 120 units. Assuming that the relationship between the weekly demand, x, and the price per unit, p, is linear Express p in terms of x How many units would they sell per week if the price were lowered to $3.05 The store has excess inventory and would like to sell 180 units this week. What price should they charge per unit to meet this goal?

The demand for gasoline can be modeled as a linear function of price. If the price of gasoline is p = $3.10 per gallon, the quantity demanded in a fixed period is q = 75 gallons. If the price rises to $3.50 per gallon, the quantity demanded falls to 45 gallons in that period. (a) Find a formula for q in terms of p. Oq = – 75p + 307.5 q = – 307.5p + 75 Oq = 75p – 157.5 q = – 75p – 157.5 Oq = 75p + 307.5

Recently there has been a rise in fatal accidents caused by “distracted driving.” The United States National Highway Traffic Safety Administration (NHSTA) defines a distraction as anything that diverts attention from driving. The following model estimates the trend in distracted driving accidents over time based on data from the NHSTA:D = 0.015t - 29.97 In this model, D is the decimal to be turned into a percentage of all fatal accidents caused by distracted driving, and t is any calendar year between 2000 and 2020. Use the model to estimate the rate for 2005 and 2020. Note: this means to plug n 2005 for t and simplify and then turn your answer into a percent. Then plug in 2020 for t and simplify and then turn your answer into a percent.
