Question

The total daily profit P, in dollars, from making and selling .x number of large

salted bagels is given by the function P(x) = 7x- (5x + b), where b is a constant.
If 300 bagels were made and sold Saturday for a total profit of $250, what is the
value of b?

Answer 1

b=350

Step-by-step explanation:

p(x)=250

250=7x-(5x+b)

*replace x with amount of bagels*

250=7(300)-(5(300)+b)
*break parenthesis*

250=7(300)-5(300)-b
*solve parenthesis*

250= 2100-1500-b

250=600-b
*isolate the variable*

b=600-250

b=350
