Answer:

{16, +infinity}

Step-by-step explanation:

Represent the number with n

Required

Find the solution set

According to the question, it states that;

4½n - 9½ > 62.5

Transform all numbers into decimals

4.5n - 9.5 > 62.5

Add 9.5 to both sides

4.5n - 9.5 + 9.5 > 62.5 + 9.5

4.5n > 72

Multiply both sides by 2

2(4.5n) > 72 * 2

9n > 144

Multiply both sides by ⅑

⅑ * 9n > 144 * ⅑

n > 16

This means that n ranges from positive 16 to infinity;

Hence, the solution set is {16, +infinity}

Svet_ta [12734]

Response:

The Work In Progress (WIP) limit is set at 0.50 days.

Detailed explanation:

Calculating WIP limits:

first, it is essential to determine the efficiency of the process and procedure, which can be calculated as follows:

Value Added Time = 12 days (arrival time)

Non-Value-Added Time = 12 days (departure time)

Efficiency = Value Added / (Value Added + Non-Value Added)

                = 12 / (12+12)

                = 12 / 24

               = 0.50 or 50%

the minimum required throughput time is 0.25 days to achieve the maximum profits

WIP limit = Throughput time / Efficiency

               = 0.25 / 50%

               = 0.50 days.

The WIP limit is 0.50 days.

Herbert plans to use the earnings from his lemonade stand according to the table above, for the first month of operations. If he
Svet_ta [12734]

The table is included below

Based on the table, we can observe that the cost of lemons contributes to 35% of the expenses.

Let x represent the expenses; hence, the lemon cost is 70.

The lemon cost is 35% of x.

So, 70 = 35% of x (where 35% = \frac{35}{100} = 0.35).

Thus, 70 = 0.35 * x.

Solving that gives us x = \frac{70}{0.35}

x = 200, meaning the expense is $200.

Given that the profit margin is 15% = \frac{15}{100} = 0.15,

we calculate profit as the product of the profit percentage and expenses.

Profit equals 0.15 * 200 = 30.

Therefore, the profit amounts to $30
