. The student council started the year with a balance of −$15 (they were in debt), but after they came up with the idea to sell tickets to a student vs. faculty mud fight, the fund grew by $15 a minute. By the time the student council had a balance of $90, how long had they been selling tickets?

Please Help Me I need a Good Grade.

they have been selling tickets for 7 minutes.

Step-by-step explanation:

Let x represent the number of minutes for which they sold tickets.

The student council started the year with a balance of −$15.

By selling tickets to a student vs. faculty mud fight, the fund grew by $15 a minute. It means that in x minutes, the funds would be

15 × x = $15x

By the time the student council had a balance of $90. The expression would be

- 15 + 15x = 90

15x = 90 + 15

15x = 105

x = 105/15

x = 7

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !
