say total hummus plates - m
cost price for each = a $
selling price for each = p $
profit for 1 plate = p - a
6.06 = p - a
p = 6.06 + a
we got selling price in terms of cost price.
he sells m plates.
revenue = m * (6.06+a)
profit= revenue- cost = m(6.06+a) - ma
m (6.06+ a-a)
profit = 6.06m
we know total he sold 214 of plates and packs. since plates we assumed as m, so packs will be 214-m
cost for each = b
sp for each = q
profit = q-b
0.79 = q-b
q= 0.79 + b
now total revenue for 214-m packs = (0.79 + b) (214-m)
profit = (0.79 + b) (214-m) - (214-m)b
= (214-m) (0.79)
now need to find that,
total profit > 700
profit from plates + profit from packs > 700
60.0m + (214-m)(0.79) > 700
solving this we get,
m>100.74
so we need to find m is greater than 100 or less than?
s-1
214-m > m
214> 2m
107>m
m< 107
this is yes or no. not a definitive ans. reject.
s-2
m < 64
this is definitely less than 100.
so this is sufficient.
choice B alone is sufficient.

Bo profits $6.06 every time he sells a plate of hummus and $0.79 every time he sells a pack of pita. Yesterday, Bo only sold plates of hummus and packs of pita, and he sold a total of 214 plates and packs. Was Bo's profit more than $700 yesterday?
(1) Bo sold more packs than plates yesterday.
(2) Bo sold fewer than 64 plates yesterday.
