Paraphin [41]

Answer:

C. 350

Step-by-step explanation:

A sample of 50 different coloured balls are removed from total golf balls made.

Out of these 50 coloured balls, 8 balls are pink

Now, to calculate the total number of golf balls made,

we can use the concept of proportion

$\frac{number of pink colored balls in sample}{total pink colored balls made}$ = $\frac{number of golf balls taken out as a sample}{ total number of golf balls made}$

$\frac{8}{56} = \frac{50}{total golf balls made}$

total golf balls made = $\frac{50\times56}{8}$

total golf balls made = 350
