if Marianne's father calls and says he needs 13 pounds of potting soil, how many additional bags should she buy?

Answer: Ana should produce more fudge, and Leo should produce more toffee.

Step-by-step explanation:

Comparative advantage defined: A person or country has a comparative advantage producing a good if their opportunity cost for it is lower than someone else's.

In this case, Ana and Leo will both benefit if they focus on the product for which they have the lower opportunity cost.

(a) Ana’s production possibilities:

If she spends all her time making fudge: 3 pounds; or toffee: 2 pounds.

Opportunity cost of 1 pound fudge = 2/3 = 0.66 pounds toffee

Opportunity cost of 1 pound toffee = 3/2 = 1.5 pounds fudge

(b) Leo’s production opportunities:

All time making fudge: 4 pounds; or toffee: 5 pounds.

Opportunity cost of 1 pound fudge = 5/4 = 1.25 pounds toffee

Opportunity cost of 1 pound toffee = 4/5 = 0.8 pounds fudge

Since Ana’s opportunity cost for fudge is lower than Leo’s, she should specialize in fudge production.

Conversely, Leo has a lower opportunity cost for toffee, so he should focus on producing toffee.

The correct option is C) $197,263.70. It has decreased 6% annually over the last three years.

Given:
Initial dog treat: 8 inches in length, 3.2 inches in width.
Miniature dog treat: 3 inches long,? wide

We will apply cross multiplication to find the proportionality:

Relating length and width.
Original treat: 8/3.2
Miniature treat: 3/x

8/3.2 = 3/x

Cross multiply:
8 * x = 3.2 * 3
8x = 9.6

Calculate x
x = 9.6/8
x = 1.2

The width of the miniature dog treat measures 1.2 inches.

To verify:
original treat: 8/3.2 = 2.5
miniature treat: 3/1.2 = 2.5
or:
8/3.2 = 3/1.2
8 * 1.2 = 3.2 * 3
9.6 = 9.6

Answer:

The male to female nurse ratio in simplest form is: 2:5

Step-by-step explanation:

Fact: A hospital has a total of 250 registered nurses.

Total number of male nurses is 100

Total number of female nurses is 250 - 100 = 150 [Total nurses minus number of male nurses]

To determine the ratio of male to female nurses in simplest terms;

A ratio indicates the relative proportions of two or more quantities.

Thus,

=

or

= = 2:5

Consequently, the male to female nurses ratio in simplest form is; 2:5

Response:

3.0

Detailed breakdown:

1(0.1) + 2(0.2) + 3(0.3) + 4(0.4) equals 3.0
