A middle school took all of its 6th grade students on a field trip to see a play at a theater that has 3220 seats. The students left 1771 seats vacant. What percentage of the seats in the theater were filled by the 6th graders on the trip?

45%

Step-by-step explanation:

to find the number of seats they took up, 3220-1771 = 1449.

now find the percent of the total that is, 1449/3220 = 0.45 = 45%

step-by-step explanation:

b and c

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
