It is a hot day at the beach. Ice water costs $1 per bottle and this is your only option. Your marginal benefit for water follow
Trava [24]

Answer:

9 bottles of water

Step-by-step explanation:

Marginal benefit is a microeconomic concept that explains how much the consumer adds satisfaction to each unit consumed of a given product. Usually, the marginal benefit is decreasing, which makes logical sense, the more a customer consumes a particular good, the smaller the benefit of the next unit.

At first, the first bottle of water has a high benefit as mentioned in the exercise:  9

In the second, you are a little less thirsty, so the benefit will be 10 - 1x2 = $8

In the ninth bottle, you will have very little thirst and the benefit will be 10 - 1x9 = $1

In the tenth bottle there is no benefit, the consumer is indifferent. As a rational consumer, you will buy until the bottle is still usable, even if minimal, for 9 bottles when your benefit is $1.

Chase answers 3/4 of his math questions correctly. There were 40 questions on the test.
lawyer [7]
Since there were 40 questions on a math quiz and he got 3/4 correct he got 30 correct and 10 incorrect.
A simple way to solve this is to add a zero to the end of each number in the fraction since there is 40 questions so it goes from 3/4 correct to 30/40 correct.
Hope this helps!!

at the dade county fair, the williams family bought 6 burgers and 4 gatorades for $14.10. the jackson family bought 3 burgers an
torisob [31]

Answer:

The cost of a burger is $1.65 and the cost of a gatorade is $1.05.

Step-by-step explanation:

We can solve this question using a system of equations.

I am going to say that:

x is the price of a burger.

y is the price of a gatorade.

6 burgers and 4 gatorades for $14.10

This means that 6x + 4y = 14.10

3 burgers and 4 gatorades for $9.15.

This means that 3x + 4y = 9.15

Will write 4y as a function of x.

4y = 9.15 - 3x

Replacing in the first equation:

6x + 4y = 14.10

6x + 9.15 - 3x = 14.10

3x = 4.95

x = \frac{4.95}{3}

x = 1.65

And

4y = 9.15 - 3x

4y = 9.15 - 3*1.65

4y = 4.2

y = \frac{4.2}{4}

y = 1.05

The cost of a burger is $1.65 and the cost of a gatorade is $1.05.
