The number of student's ticket sold is 200.

Two equations can be gotten from the question:

a + b = 375 equation 1

7.5a + 4.5b = 2,212.50 equation 2

Where:

a = number of adult ticket sold

b = number of children's ticket sold

In order to determine the value of b, multiply equation 1 by 7.5

7.5a + 7.5b = 2812.50 equation 3

Subtract equation 2 from 3

3b = 600

Divide both sides by 3

b = 600 / 3

b = 200

14. Suppose that the production of $1 million worth of steel in Canada requires $100,000 worth of taconite. Canada’s nominal tar
VMariaS [17]

Answer:

The effective rate of protection for Canada’s steel industry is 21%

Explanation:

The computation of the effective rate is shown below:

Steel percentage = (Production worth of steel) ÷ (Taconite worth)

                             = ($1,000,000) ÷ ($100,000)

                             = 10%

And the tariff rate for steel is 20%

And the taconite percentage is 10%

So, the effective rate would be equal to

= Tariff rate for steel + taconite percentage × steel percentage

= 20% + 10% × 10%

= 20% + 1%

= 21%
