I think the answer is 19.5
Answer:
t=15/4 or 3.75
Step-by-step explanation:
t x 3/15 =3/4
t x 3/15 ÷3/15 = 3/4 ÷3/15 (Divide each side by 3/15)
t= 3/4 x 15/3
t=15/4 or 3.75
Answer:
The equation of line for given points is y = - 40 x - 42
Step-by-step explanation:
Given two points as :
( -1 , - 2 ) and ( 3 , - 162 )
Now, Equation of line in points form
y -
= m × ( x -
)
Where m is the slope of line
And, m = 
or, m = 
or, m = 
∴ m = - 40
So, Slope of line for given points is - 40
Now equation of line can be written as
y - ( - 2 ) = ( - 40 ) × ( x - ( - 1 ) )
or, y + 2 = ( - 40 ) × ( x + 1 )
or, y + 2 = - 40 x - 40
or, y = - 40 x - 40 - 2
∴ y = - 40 x - 42
Hence the equation of line for given points is y = - 40 x - 42 Answer
50,000 / 2500 = 20....he bought them for 20 bucks a piece. So if he wants to sell them at 15% profit, he would sell them for 20 + 0.15(20) = $ 23 bucks.
A 15% profit of 50,000 dollars is 0.15(50,000) = 7500. Plus the 50 grand spent totals 57500. So they want to make a $ 7500 profit. Selling 2500 lamps at $ 23 per lamp (2500 x 23 = 57500) makes them their profit.
I should just shut up now...answer is $ 23 per lamp
