The latest demand equation for your yoda vs. alien t-shirts is given by: q = −40x + 800 where q is the number of shirts you can sell in one week if you charge $x per shirt. the student council charges you $400 per week for use of their facilities, and the t-shirts cost you $4 each. find the weekly cost as a function of the unit price x.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
