Let's make a system of equations.
1 large bottle = l
1 regular bottle = r
l + r = 113
221 = 2.5l + r
Isolate r in the first equation and substitute it into the second equation:
l + r = 113
r = 113 - l
---
221 = 2.5l + 113 - l
221 = 1.5l + 113
108 = 1.5l
72 = l
Now, substitute that back into the first equation:
l + r = 113
72 + r = 113
r = 41
Finally, check your work by substituting back into both equations:
72 + 41 = 113 --> 113 = 113 <-- True
221 = 2.5(72) + 41 --> 221 = 180 + 41 <--True
Answer:
Franklin sold 72 large bottle of water and 41 regular-sized bottles of water.
Answer:
313 in.
Step-by-step explanation:
V = r × h
10,000 = 32 × ?
10,000 / 32 = 312.5
312.5 rounded to the nearest whole number is 313 in.

Answer:
1. 7
2. 5/8
3. 5
4. 20
Step-by-step explanation:
There is one burger that weighs 3/8 pounds, four that weigh 1/2 pound, and two that weigh 3/4 pounds. The difference between the heaviest and the lightest is 3/4-1/8=5/8. The total combined weight is 5 pounds. 5/ 1/4= 5*4=20. Hope this helps!
