# this program is designed to introduce grade 9 students 
# to some topics of linear equations
# it is based on a group problem found on my website
# at https://www.markrussell.name/teaching/
# email: mrussell@ebrschools.org
# Students will be expected to write this as a function
# using PyCharm community edition as a homework exercise

# get values for the input variable and constants according to
# the instructions on the group handout

# input the per unit sales price in x.xx format
unitSP = float(raw_input("Enter a per unit sales price: "))

# input the number of units sold as an integer
numS = int(raw_input("Enter the number of units sold: "))

# input the fixed costs calculated in the group work
# session in x.xx format
fixedC = float(raw_input("Enter the fixed costs: "))

# calculate the profit
calcP = unitSP * numS - fixedC

# output the input data and the
# associated calculated output data
     
print "For per unit sales price = $", unitSP, " and,\n"
print "number of units sold = ", numS, " and, \n"
print "fixed costs = $", fixedC, ",\n"
print "I should realize a profit of $", calcP, "."

# using the results of your calculations
# answer the questions in you group handout
