Answer: He made $90 last week.
Assumption :
Let, Luis made $X last week.
He made $72 this week which is 80% of $X that he made last week
⇒ X * 80% = 72
⇒ X * 80/100 = 72
⇒ X = (72 * 100)/80
⇒ X = 90

The probability that the selected consumer is 35–55 years old or likes Crunchicles is 0.444.
Number of people who liked Crunchicles = 121
Number of people who are 35 - 55 years of age = 120
Number of people who are 35-55 years of age or like crunchicles = 121 + 120 - 19
The probability that the selected consumer is 35–55 years old or likes Crunchicles = 222/500 = 0.444.
