Rosa has already eaten 10 pretzels from a bag that originally contained p pretzels. If Rosa is able to eat each remaining pretzel in 18 seconds, which of the following represents the amount of additional time, in seconds needed for Rosa to eat all the pretzels in the bag? A) 10(18-p) B) 10(p-18) C) 18(10-p) D) 18(p-10)

To find the amount of additional time needed for Rosa to eat all the pretzels in the bag, we need to calculate the time it takes for her to eat the remaining pretzels.<br /><br />Given that Rosa has already eaten 10 pretzels from a bag that originally contained p pretzels, the number of remaining pretzels is (p - 10).<br /><br />Since Rosa is able to eat each remaining pretzel in 18 seconds, the amount of additional time needed for Rosa to eat all the pretzels in the bag is represented by the expression 18(p - 10).<br /><br />Therefore, the correct answer is D) $18(p-10)$.
