(11−4)+3×11−4−5 B. (11−4)+3×(11−4)−5 C. (11−4)+3−4×11−5 D. (11−4)+3−5×(11−4)
Part B How many songs do they need for their show? A. 39 songs B. 31 songs C. 25 songs D. 23 songs.

Answer 1

Answer: they need 28 songs for their show, which corresponds to option D.

Explanation:

The expression for the number of songs they need for their show is (11-4) + 3×(11-4) - 5, which corresponds to option B.

To find how many songs they need for their show, we can evaluate the expression:

(11-4) + 3×(11-4) - 5 = 7 + 3×7 - 5 = 7 + 21 - 5 = 28.
