Answer:
$9.25
Step-by-step explanation:
let x = the cost of a child ticket
3(x)+2(x+3.50)=35.75
3x+2x+7=35.75
5x=28.75

Answer is A.
step 1 , 16 was not multiplied by 9
should be

Sandi did not follow PEMDAS. She added before multiplying and dividing. Her answer should be 18 because 6 • 4 = 24, 2 / 2 = 1, 24 + 1 = 25, 25 - 7 = 18
Step-by-step explanation:
(2(x+y)÷(x+y)(x-y) )×(x+y÷(x^2+2×x×2y+2y^2)
2÷x^2+2y^2
