John Doe estimates that the price elasticity of demand for new SUVs to be 0.75. If the price of SUVs rose by 15%; would the quan
Charra [1.4K]
If the coefficient of demand for the SUV is 0.75 this means that it has a relatively inelastic demand since it is less than. In other words, there is only a little alteration in demand when prices change.
So when the price of SUV rise by 15%, and it has a coefficient of 0.75, we can anticipate only 11.25% decrease in its demand. This is for the reason that the SUVs do not have many substitutes for it.
So to solve:
(x/15%) = 0.75
Then simply solve for x:
 x = (0.75)(0.15) = 11.25%

A square has a side of 5 ft. What is<br> the perimeter of the triangle?
luda_lava [24]

I'll draw it for you cause im nice.

Ok so if you have 5ft on a square, all the sides are 5ft.

That mean that if its in half, one of the sides will be 2.5ft.

Now you can add 2.5 + 2.5 + 5+5 = 15.

So its 15 ft.

AysviL [449]

Answer:

9 hours

Step-by-step explanation:

Let :

Landon hours = x

Ben hours = y

x + y = 14 - - (1)

60x + 56y = 820 - - - (2)

From (1)

y = 14 - x

60x + 56(14 - x) = 820

60x + 784 - 56x = 820

4x = 820 - 784

4x = 36

x = 36/4

x = 9

Landon drove for 9 hours
