Question

Of the customers who purchased regular gas, 10% pald in cash, whereas 20% of the customers who did not purchase regular gas paid in cash. What percentage of the customers paid in cash? O30% O 28% O 14% O 12%​

Answer 1

Answer: O 12%

Step-by-step explanation:

Let's assume that 100 customers visited the gas station that day. According to the given information, 80% of them purchased regular gas, which means 80 customers bought regular gas.

Of those 80 customers, 10% paid in cash, which is 8 customers.

The remaining 20 customers did not purchase regular gas, and 20% of them paid in cash, which is 4 customers.

Therefore, the total number of customers who paid in cash is 8 + 4 = 12.

The percentage of customers who paid in cash out of the 100 customers who visited the gas station that day is 12%, so the answer is O 12%.

Answer 2

To find the percentage of customers who paid in cash, we need to use the given information to calculate the probability of a customer purchasing gas with cash.

Let's assume that there were 100 customers in total. Of these, 80% purchased regular gas, so 80 customers purchased regular gas. Of these 80 customers, 10% paid in cash, which means that 8 customers purchased regular gas with cash.

Of the remaining 20 customers who did not purchase regular gas, 20% paid in cash, which means that 4 customers purchased gas other than regular gas with cash.

Therefore, the total number of customers who paid in cash is 8 + 4 = 12. Since there were 100 customers in total, the percentage of customers who paid in cash is:

12/100 * 100% = 12%

Therefore, the answer is 12%, option D.
