Answer:
160 sandwiches/hour
Step-by-step explanation:
To find his unit rate, divide 400 by 2.5, since he can make 400 sandwiches in 2.5 hours:
400/2.5
= 160
This means he can make 160 sandwiches in 1 hour.
So, his unit rate is 160 sandwiches/hour
800÷20= 40 so 40 winners per draw.
19/20 as a percent is 95%
So 1. 40
2. 95%
Hope this helps!
