Agroup of people go to a play adult tickets cost $8 and tickets for children cost $5. there are4 children attending the play. the total cost for tickets for the entire group is $76. how many adults attend the play?

Step-by-step explanation:

A =adults

C = children

$8*A + $5*C = $76

So there are 4 children

$8*A + $5*4 = $76

$8*A + $20 = $76

$8*A = $76 - $20

$8*A = $56

A = 56/8 = 7

There are  7 adults attending the play.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
