For (29-31). A Lechon Manok store has an average of 5,000 customers per
week and sells for P225 per whole - grilled chicken. Because of increased
labor and production costs, the store owner needs to increase the price of
the grilled chicken. The owner is aware of the results of the survey that for
each P10 increase in price, the number of customers decreases by 12.
29. Write a function rule that describes the increased price per
chicken
a f(x) = x +12
b. f(x) = x +25
C fix) = x+50
d fx) = x +10
30
Write a function rule that describes the reduced number of
customers after the increase in price
a f(x) = (500-12)(x+12)
b. f(x) = (500-25)(+10)
cf(x) = (500-12)(x+10)
d. f(x) = (500-50)(x+10)
31. How much income would be realized by the owner if the
decides to increase the original price to P235?
a f(235) = 1.175.000
b. f(235) = 1.172.180
c. f(235) = 1.172.650
d f235) = 1.170.000
32
