Calculate the time price elasticity of demand if people reduce their physician visits by 20% when the travel time to get to the nearest physician is increased from 15 to 45 minutes

  -10%

Step-by-step explanation:

  price elasticity of demand = % change in demand / % change in price

Here, the "price" changes from 15 to 45, so its percent change is ...

  ((new value)/(old value) -1) × 100%

  = (45/15 -1) × 100%

  = 200%

The % change in demand is given as -20%, so the price elasticity is ...

  price elasticity of demand = (-20%)/(200%) = -0.10 = -10%

dude   i don't even know. i've been trying for hours.

step-by-step explanation:

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510
