Question

Describe how to find the number of seats in the middle and lower levels of the stadium when solving for the variable only gives the number of seats on the upper level.

Answer 1

Explanation:

To find the value of the upper level you would have to solve the equation "x + (2x + 40) + (3x – 50) = 15,002" and the answer is 2,502. But to find the values of the middle and lower floors you need to apply the variable to separate equations. The lower level has 50 fewer than three times as many seats as the value of x. So to find the number of seats in the lower levels, you would have to multiply 2,502 by 3 (7,506) and subtract 50 (7,506 - 50 = 7456). The middle level has 40 more than twice as many seats as the upper level. To find the middle level you would multiply 2,506 by 2 (5004) and add 40 ( 5004 + 40 = 5044).
