Billy anderson is choosing between two fitness centers. Center A charges $495 per year for unlimited use of all facilities. Cent
er B charges a $25 sign up fee, a $15 monthly fee, and $5 per aerobics class. If billy goes to aerobics once a week, which club is least expensive for him to use for a year
It would be cheaper for Billy Anderson to go to Center B because the 25 dollar sign up fee plus the 15 dollars a month for 12 months plus 5 dollars a week for 52 weeks is 25+180+260 is 465 so he would save $30 dollars
yes, there are infinitety many polynomial that have exactly one real root just like your example, to determine the real root first let the real root is a, and the complex roots are b±ic the polynomial satisfy
-9x³ + 19x² + 17 = -(x - a)(x - b - ic)(x - b + ic)
dollars a year
dollars a year (given that Billy goes to class once a week) (<em>Note: There are 52 weeks in a year</em>)
