Problem 1: Total weight of generators
Question: The total weight of 15 generators is 2175 kg. What is the weight of each generator?
Solution:
To find the weight of each generator, we need to divide the total weight by the number of generators.
\[
\text{Weight of each generator} = \frac{\text{Total weight}}{\text{Number of generators}}
\]
Substitute the given values:
\[
\text{Weight of each generator} = \frac{2175 \, \text{kg}}{15}
\]
Perform the division:
\[
\frac{2175}{15} = 145
\]
Thus, the weight of each generator is:
\[
\boxed{145 \, \text{kg}}

Problem 2: Cost of flower vases
Question: Daniel bought 9 flower vases for $747. What is the cost of each vase?
Solution:
To find the cost of each vase, we need to divide the total cost by the number of vases.
\[
\text{Cost of each vase} = \frac{\text{Total cost}}{\text{Number of vases}}
\]
Substitute the given values:
\[
\text{Cost of each vase} = \frac{747}{9}
\]
Perform the division:
\[
\frac{747}{9} = 83
\]
Thus, the cost of each vase is:
\[
\boxed{83 \, \text{dollars}}

Problem 3: Per-hour wage
Question: On a daily basis, Richa earns $136 if he works for 8 hours. What is the per-hour wage?
Solution:
To find the per-hour wage, we need to divide the total daily earnings by the number of hours worked.
\[
\text{Per-hour wage} = \frac{\text{Total daily earnings}}{\text{Number of hours worked}}
\]
Substitute the given values:
\[
\text{Per-hour wage} = \frac{136}{8}
\]
Perform the division:
\[
\frac{136}{8} = 17
\]
Thus, the per-hour wage is:
\[
\boxed{17 \, \text{dollars}}

Problem 4: Number of people per table
Question: 81 people sat on 9 tables. Each table had an equal number of chairs. How many people sat at each table?
Solution:
To find the number of people sitting at each table, we need to divide the total number of people by the number of tables.
\[
\text{Number of people per table} = \frac{\text{Total number of people}}{\text{Number of tables}}
\]
Substitute the given values:
\[
\text{Number of people per table} = \frac{81}{9}
\]
Perform the division:
\[
\frac{81}{9} = 9
\]
Thus, the number of people sitting at each table is:
\[
\boxed{9}

Problem 5: Cost of each box of juice
Question: Phillips sold 24 boxes of juice and earned a total of $345. What is the cost of each box of juice?
Solution:
To find the cost of each box of juice, we need to divide the total earnings by the number of boxes sold.
\[
\text{Cost of each box of juice} = \frac{\text{Total earnings}}{\text{Number of boxes sold}}
\]
Substitute the given values:
\[
\text{Cost of each box of juice} = \frac{345}{24}
\]
Perform the division:
\[
\frac{345}{24} = 14.375
\]
Thus, the cost of each box of juice is:
\[
\boxed{14.38 \, \text{dollars}}
\]
