A. P(x) = x4 - 8x3 + 14x2 - 678x + 2380 B. P(x) = x4 - 339x2 + 1356x - 2380 C. P(x) = x4 - 87x2 + 1356x - 2380 D. P(x) = x4 - 8x3 - 14x2 + 678x - 2380
Provide an appropriate response.Roberto is an employee of a store and receives 20% discount off all items in the store. During a sale, the price of a jacket is reduced by $15. Roberto will receive both his 20% discount and the $15 off. Which is better for Roberto, to take the 20% discount first and then subtract $15 or to subtract $15 first and then take his 20% discount?
