Answer

Explanation:

Step1: Calculate total customers last week

$76 + 4+42=122$

Step2: Calculate the proportion of cash - paying customers

The proportion of cash - paying customers last week is $\frac{76}{122}$.

Step3: Estimate cash - paying customers next week

Multiply the proportion by the expected number of customers next week. So the expected number of cash - paying customers next week is $\frac{76}{122}\times200=\frac{15200}{122}\approx125$.

Answer:

125
