"¢ # of customers ordered special on Monday = 12% of 180 = 36;
"¢ # of customers ordered special on Tuesday = 10% of 120 = 12

Total # of customers who ordered special on both days = 36 + 12 = 48;
Total # of customers on both days = 180 + 120 = 300;

Percent of the customers ordered the daily special = (48/300)*100% = 16%

The correct answer: B

Hope this helps!

On the first day, 0.2 x 180 = 36 customers ordered the special.

On the second day, 0.1 x 120 = 12 ordered the special.

We combine the data for the two days. Thus, (36 + 12)/(180 + 120) = 48/300 = 0.16 = 16% of the customers ordered the special.

On a Monday in a certain restaurant, 20 percent of the 180 customers ordered the daily special.
10% of 180 = 18
So, 20% of 180 = 36
So, 36 people ordered the daily special on MONDAY

On Tuesday, only 10 percent of the 120 customers ordered the special.
10% of 120 = 12
So, 12 people ordered the daily special on TUESDAY

For the two days combined, what percent of the customers ordered the daily special?
TOTAL number of people who ordered the daily special = 36 + 12 = 48 people
TOTAL number of customers for the two days = 180 + 120 = 300

So 48/300 of the customers ordered the special.
Our job is to rewrite 48/300 as a PERCENT. Here's one approach:
Take: 48/300
Divide top and bottom by 3 to get the EQUIVALENT fraction 16/100
16/100 = 16%

Answer: B
