Question

A cafe is open for six days a week. There was a mean number of 86 customers for five days. On the next day there were 122 customers. What is the mean number of customers over the six days?

Answer 1

Answer:

92

Step-by-step explanation:

The mean is calculated as

mean = $\frac{sum}{count}$

The sum of customers over the 5 days is

$\frac{sum}{5}$ = 86 ( multiply both sides by 5 )

sum = 430

Thus mean over the 6 days is

mean = $\frac{430+122}{6}$ = $\frac{552}{6}$ = 92
