The diaper service where you work bills customers once a week. Each week, the diaper service charges 30¢ each for the first 75 diapers used and 25¢ each for any additional diapers. How much should you bill a family that used 100 diapers last week?

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
