They are twice as many children as adults at the concert the total amount of money collected for the concert is 1080 how many adults are at the concert

360 Adults

Step-by-step explanation:

Let's represent the number of Adults with x.

Number of children = 2 * x = 2x.

The total amount collected for both children and adults = 1080.

Therefore, to know the number for adults we use the expression:

x + 2x = 1080

3x = 1080

Divide through by 3

x = 1080/ 3

x = 360.

Therefore, there are 360 adults.

Children would 2x

= 2*360

=720

94

step-by-step explanation:

(79+94+91+92+x)/5=90

x = 94
