At a charity​ fund-raiser, adult tickets were sold for ​$10 each and​ children's tickets were sold for $4 each. Write an algebraic expression for the total amount of money raised from the sale of tickets. How much money was raised if the fundraiser sold 244 adult tickets and 387 ​children's tickets?

The total money raised was $2,414

Step-by-step explanation:

Let

x > the number of adult tickets

y > the number of children's tickets

we know that

The algebraic expression that represent the total amount of money raised from the sale of tickets  is

7x+2y

For x=234, y=388

substitute in the algebraic expression

7(234)+2(388)=$2,414

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
