Question

suppose our school is having a talent show to raise money for new music supplies .you estimate that 200 students and 150 adults Will attend. you estimate $200 in expense. write an equation to find what ticket prices you should set to raise exactly $1,000

Answer 1

Maybe something like:
200s + 105a + 200 = 1,000
You can use x and y instead of s for student and a for adult.
Are the adults and students charged the same? If so then:
200x + 105x + 200 = 1,000

Answer 2

The answer is 3x-x+2=4
