You have 100 people. 90 have French heritage, 80 have English heritage and 75 have Native American heritage, how many have herit
USPshnik [31]
My answer is 82. I added up 90 + 80 + 75 = 245. I then divided that by 3 because there are 3 different cultures. And the number was 81. something. So, I rounded and got 82. But I'm not sure if that's the right answer.

Justin earns 5% commission on his real estate sales. One year, his total commission was 35,750. What were his sales for that yea
Ymorist [56]

The sales for the particular year was: 715000

Step-by-step explanation:

We will use the percentage formula for finding the total sales.

Given

Commission Rate = 5%

Commission = 35750

Let x be the sales

So,

Commission=Sales * 5\%\\35750=x * \frac{5}{100}\\35750=x * 0.05\\x = \frac{35750}{0.05}\\x= 715000

The sales for the particular year was: 715000

First tour is 4 child tickets and 8 adult tickets for 128 dollars second tour is 6 adult tickets for 72 dollars what is the pric
V125BC [204]

Answer:the price of one child ticket is $8

the price of one adult ticket is $12

Step-by-step explanation:

Let x represent the price of one child ticket.

Let y represent the price of one adult ticket.

First tour is 4 child tickets and 8 adult tickets for 128 dollars. This means that

4x + 8y = 128 - - - - - - - - - - 1

Second tour is 6 adult tickets for 72 dollars. This means that

6y = 72

y = 72/6 = $12

Substituting y = 12 into equation 1, it becomes

4x + 8 × 12= 128

4x + 96 = 128

4x = 128 - 96

4x = 32

x = 32/4 = $8
