Answer

Explanation:

Step1: Calculate total number of customers

$50 + 50+70 + 30=200$

Step2: Calculate number of hockey - skate renters

$50 + 30 = 80$

Step3: Calculate percentage of hockey - skate renters

$\frac{80}{200}\times100%=40%\neq50%$

Step4: Check total number of surveyed customers

Total is 200, not 100

Step5: Calculate percentage of adult hockey - skate renters

$\frac{30}{200}\times100% = 15%$

Step6: Calculate percentage of children figure - skate renters

$\frac{50}{50 + 50}\times100%=50%\neq25%$

Answer:

Of all the customers, 15% rented hockey skates and are adults.
