Question

A gas station employee monitored the gas sales one day. The data showed that 80% of customers purchased regular gas. Of the customers who purchased regular gas, 10% paid in cash, whereas 40% of the customers who did not purchase regular gas paid in cash. What percentage of the customers paid in cash? 48% 20% 16% 50%

Answer 1
