Answer: 20 days
Step-by-step explanation:
Since the sale agent makes 40 calls a day and about 15% he calls result in a sale. This means the number of sales will be:
= 15% × 40
= 0.15 × 40
= 6
6 sales out of every 40 calls per day.
The number of calls to make 120 sales will be:
= 15% of x = 120
0.15 × x = 120
0.15x = 120
x = 120/0.15
x = 800 calls
Since he needs 800 calls and he makes 40 calls per day, the number of days needed will be:
= 800/40
= 20 days
The answer is 2, because it is asking you, out of the 30 people, who is being counted twice for brown hair and blue eyes. Therefore, you add 17 and 15 to get 32, and because there are only 30 people in the class, you do 32 - 30 = 2 people. Let me know if you're confused or anything :)
