Movie tickets are \$7 for students and \$9 for adults. A group of 8 people spent \$66 on movie tickets. How many adult tickets were bought?

• Math - ,

student tickets --- 8-x

solve for x

9x + 7(8-x) = 66

• Math - ,

9 x 5 adults + 7 (8-5)= 66

45 + 7 (3)kids = 66
45 + 21 = 66

Now I found 5 adults by multiplying 9 x 5=45 just because that's the only way I know... Now I have no idea how to find x other than that. I am trying to help my 3rd grader with that. Please help.

You can take the 8 people and start by subtracting out 2 students. X that by the cost of the student ticket then take the 6 left from the 8 people and X that by the cost of the adult ticket. This you will find is to much spent. Next, you can take the 8 people and use the next number(3) X that by the cost of the student ticket then take the 5 left from the 8 people and X it by the cost of the adult ticket and you will see that this equals the \$66.00 total spent. So this shows that 3 student tickets and 5 adult tickets were bought for the total of \$66.00.
