The answer is between $175 and $295. The standard deviation rule tells us that for distributions that have the normal shape, approximately 99.7% of the observations fall within 3 standard deviations of the mean. Indeed, 175 = 235 − 3 * 20 and 295 = 235 + 3 * 20 are exactly 3 standard deviations below and above the mean, respectively.

Answer:
B. -80x + 28y - 56
D. 4(-20x + 7y - 14)
Step-by-step explanation:
8(-10x + 3.5y - 7)
= 8(-10x) + 8(3.5y) - 8(7)
= -80x + 28y - 56
= 4(-20x + 7y - 14)
