Answer:
Paid on time: 0.654 or 65.413%
Paid late: 0.175 or 17.450%
Unpaid: 0.066 or 6.583%
Step-by-step explanation:
Paid on time: These were paid on time, so the question tells us 626 fit that requirement. Plugging in 626/ the total of 957 in the calculator results in getting 0.654 or 65.413%
Paid late: 123 were paid up to 30 days late and 145 were paid between 31 and 90 days. The question asks for the bills that were payed but late, so we can add 123 and 145 together to get 167. We can again do 167/957 to get 0.175 or 17.450%
Unpaid: 63 were unpaid. Meaning doing 63/957 gets 0.066 or 6.583%
