Answer:
54 oz. OR 3 3/8 lbs.
Step-by-step explanation:
1) Convert pounds to ounces. There are 16 ounces in a pound. 20 * 16 = 320.
2) Add the remaining 4 ounces. 320 + 4 = 324.
3) Divide 324 by 6. 324/6 = 54.
Final answer: 54 ounces.
NOTE: If you want the answer in pounds, divide 54 by 16. 54/16 = 3 3/8
Final answer b: 3 3/8 pounds
Create formulas!
x=number of adult tickets
y=number of student tickets
x+y=644 <em>total sold</em>
56+y=x <em>student was 56 less than adult</em>
Perform substitution
(56+y)+y=644
56+2y=644
2y=588
y=294
Substitute y into the formula we created
x+294=644
x=350
350 adult tickets were sold.

Answer: 13</h3>
=========================================================
Explanation:
We're told that there are 50 people in each grade that are surveyed. So that means 50 eighth graders were surveyed.
Add up the values along the bottom row. Set the sum equal to 50 and solve for m
m+8+29 = 50
m+37 = 50
m = 50-37
m = 13
Then note how 13+8+29 = 50 along the bottom row. Also, for the top row we have 17+15+18 = 50 as well.
