Answer:
4 bars
Step-by-step explanation:
Gail's ratio of bars to bottles is ...
20 : 15 = 4 : 3
For 3 bottles, she should pack 4 bars.
4(4x+1)=(3x-46-x)+8
16x+4=3x-46-x+8
16x-3x+x=-46-4+8
14x=-42
14x/14=-42/14
x=-3
112 people
= write the proportion where x is the number of people with a missplaced time
50x = 5600 cross multipy
x = 112 divide both sides by 50
6.4 is the answer that is the answer
3 hours and 45 minutes
