"The security door passcode," said Miranda, "is a seven-digit number whose digits total 35. The 4th digit is 3 more than the 1st digit, the 5th digit is 4 more than the 2nd digit, the 6th digit is one less than the 4th digit, the last digit is one less than twice the 2nd digit, and the sum of the 1st and 3rd digits is one more than the 4th digit." Miranda continued, "However, the passcode has no repeated digits." What is the security door's passcode? *

100 + (5X) = -2X

Step-by-step explanation:

Since the club with an occupancy of 100 will sell out at $ 25 per ticket, and if the owner decides to increase the price by $ 5, then 2 less tickets will be sold, to determine the revenue function if X is the number of $ 5 increases the following calculation must be performed:

100 + (5X) = -2X

So, for example, if the price were increased by $ 15, the equation would apply as follows:

15/5 = 3

100 + (5x3) = -2 x 3

100 + 15 = -6

115 = -6
