Adepartment store purchases screen-printed t-shirts at a cost of $5 per shirt. they mark up the price 150% (making the selling price 250% of the store's purchase price) and put them on the sales floor. every month that a t-shirt doesn't sell, the store reduces the selling price by 25%.

The table represents a function f(x). what is f(3)? a.-9 b.-1 c.1 d.9

Which of the following is the explicit rule for a geometric sequence defined a recursive formula of a -5a for which the first term is 23?
