Jamal is creating toys to sell. He is averaging 8 toys every 5 days. If he continues at this rate, how many days will it take to fill an order of 75? Round to the nearest whole number of days.

A. 10
B. 120
C. 375
D. 47

The rate of making toys is 8 toys / 5 days = <<8/5=1.6>>1.6 toys/day

The number of days to make 75 toys = 75 toys / 1.6 toys/day = <<75/1.6=46.875>>46.875 days
Rounded to the nearest whole number of days, it will take 47 days to fill the order of 75 toys.
The answer is D. 47. Answer: \boxed{D}.
