For the three days listed below, calculate the gross pay for Sarah, who is the hospital's casual diet tech, using the following information.

Correct answer: $249.50

Monday: (8 hrs x 10) + (1 hr x 0.5) = $80 + $0.50 = $80.50

Wednesday: (8 hrs x 10) + (1 hr x 0.5) = $80 + $0.50 = $80.50

Saturday: (8 hrs x 10) + ( 8 hrs x 1) + (1 hr x 0.5) = $88.50

In a hospital café, the total food purchased was $32,123, and the total café sales were $23,231. The labor expenses for the café were $25,790.

If the meal equivalent factor is $2.15, what was the labor cost per meal?

$2.38

Total number of meals served = Total café sales / Meal equivalent factor

Total number of meals served = $23,231 / $2.15 per meal = 10,801 meals

Labor cost per meal = Total labor expenses / Total number of meals served

Labor cost per meal = $25,790 / 10,801 meals = $2.38 per meal

Therefore, the labor cost per meal is $2.38.

You are planning the budget for next year. It is estimated that food costs will increase by 5%, labor costs by 12%, and overhead by 5%. Given the following information, calculate the new budget.

Sales: $1,000,000

Food Cost: 40%

Labor Costs: 40%

Overhead Cost: 20%

$1,078,000

To calculate the new budget, we need to first calculate the current food, labor, and overhead costs. Next, we need to apply the estimated percentage increases for food, labor, and overhead costs to calculate the new costs for each category.

Food cost: 40% of 1 million = $400K --> 400K x 105% = 420K

Labor cost: 40% of 1 million = $400K --> 400K x 112% = 448K

Overhead: 20% of 1 million = $200K --> 200K x 105% = 210K

Finally, we add up the new costs for each category to calculate the new budget:

$420K + $448K + $210K = $1,078,000
