An adult ticket to a museum costs $3 more than a children’s ticket. when 200 adult tickets and 100 children’s tickets are sold, the total revenue is $2100. what is the cost of a children’s ticket?

5$

Step-by-step explanation:

Lets call the childrens ticket x and the adult (x+3).

We then have the equation

200(x+3) + 100(x) = 2100

Divide all by 200

(x+3) + 1/2(x) = 10.5

Subtract 3

x + 1/2x = 7.5

Rewrite it

1.5x = 7.5

Divide by 1.5

x = 5

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

correct answer is b. 27/8
