By using the concept of profit, it can be calculated that
Profit function = 5.75 x - 1200
What is profit?
If the selling price of an article is more than the cost price of the article, the difference between the selling price and cost price gives the profit
Monthly expense for a pizza parlor C(x) = 1,200 + 6. 75x
Revenue function = 12.5x
Profit function = R(x) - C(x)
= 12.5x - (1200 + 6.75x)
= 12.5 x - 1200 - 6.75x
= 5.75 x - 1200

X + y = 4200 so x = 4200 - y
0.035x + 0.045y = 174
substitute x = 4200 - y into 0.035x + 0.045y = 174
0.035x + 0.045y = 174
0.035(4200 - y) + 0.045y = 174
147 - 0.035y + 0.045y = 174
0.01y = 27
y = 2700
x + y = 4200
x = 4200 - 2700
x = 1500
