The parent teacher organization has raised $1800 to pay for a year-end trip to an amusement park. they ask that there be one adult for every five students attending. adult tickets cost $45 and student tickets cost $30. if the group wants to take 50 students, how much will each student need to pay so that adults agreeing to chaperone pay nothing? a. $5 b. $40 c. $150 d. $3

The answer you are looking for would be D. $3

This is found by divding 50 (number of students) by 5 (number of students per chaperone). This shows there are 10 chaperones.

Multiply 10 and 45 (cost of adult tickets) to get $450. Then multiply 50 and 30 (cost of student tickets) to get $1,500.

Next you'd add 1,500 and 450 together to show the total ticket cost, which is $1,950. Since the organization raised $1,800 already, you'd subtract it from $1,950, to get $150.

Finally, divide $150 by 50 to show how much each student pays.

I hope this helps!

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
