A theater wants to take in 2000 dollars for a certain matinee. Children's tickets cost 5 dollars each and adult tickets cost 10 dollars each. If the theater has a maximum of 350 seats, write a system of equations that can be solved to determine the number of both children and adult tickets the theater can sell.

We have the following system of equations:

(2) = x = 350-y . Replace x in equation (1 )

=> 5(350-y)+10y=2000 => y = 241

Replace y=241 in equation (2 ) => x = 350-241 = 109

the number of both children and adult tickets the theater can sell.

Children tickets : 109

Adult tickets : 241

Step-by-step explanation:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
