Question 705004: Solve thw following problems. Slope-Intercept
1) A salesman makes 13 dollars per item he sells. how much does he make if he sells 8 items?
2) A cellphone company charges a flat fee of 20 dollars plus 3 cents a call. What is the total bill if there was a total of 200 calls for the month.
3) Write an equation to model the total earnings y(in dollars) in terms of x(the number of hours). Your rate for math tutoring is 9 dollars an hour. You earned $63 in 7 hours. Point-Slope
a)y-9=7(x-63)
b)y-63=(x-9)
c)y+9=7(X-630
d)y-63=9(X-7)
e)y-9=63(X-7) Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Solve thw following problems. Slope-Intercept
1) A salesman makes 13 dollars per item he sells. how much does he make if he sells 8 items?
f(x) = 13x
f(8) = 13*8 = $104.00
------------------------------
2) A cellphone company charges a flat fee of 20 dollars plus 3 cents a call. What is the total bill if there was a total of 200 calls for the month.
C(x) = 3x+2000
C(200) = 3*200 + 2000
C(200) = 2600 cents = $26.00
-----------------------------------
3) Write an equation to model the total earnings y(in dollars) in terms of x(the number of hours). Your rate for math tutoring is 9 dollars an hour. You earned $63 in 7 hours. Point-Slope
y = 9x
y-63 = 9x-63
y-63 = 9(x-7)
