RD Exam Math Equations Questions And
Answers.
Equation for straight line depreciation -
\value of the equipment (cost) - salvage value / # of years of useful life
ex: a dishwasher cost 24,000 and has a usable life of 8 yrs and a salvage value of
2400. Therefore a depreciation expense of 2700 would be claimed each year
24,000-2, = 2700
p IV 32
Nitrogen balance equation -
\Nitrogen intake (grams) /6.25 - urinary urea nitrogen loss + 4
Prime cost -
\Raw food cost + direct labor cost
Meals per labor hour -
\#meals produced/#hours worked
Popularity index -
\#servings of and item/total # servings of all items in that category that day
To determine # of oz in a scoop -
\Divide the scoop number into 32
Ex: 32/#12 = 2.67 oz
1 oz = 1/8 c
% food cost -
\Daily food cost/daily food income
FTE/ Year calculation -
\labor hours worked that year/2080
**Labor hours worked includes full-time and part-time workers
**2080 because that is 52 weeks/year x 40 hrs worked per week
Edible Portion of As Purchased Items -
\Ex: You purchase an 18# ready to cook turkey at $.068/#. The AP price is $12.24. After
cooking and slicing, EP is just 9.9#. To determine the EP cost per #, divide the
purchase cost by the edible weight.
**Raw purchase cost (AP) $12.24/Cooked edible wt 9.9# = EP cost/# $1.24
