Answer:
6
Step-by-step explanation:
To breakeven means that you made exactly as much money as you spent, so if you spent $50 to make lemonade, you would need to make $50 in profits from selling to break even
first subtract the cost of making each horse from the price of selling each horse (you do this to find out how much profits he makes from one horse):
125 - 75 = 50
now divide 300 by 50 to find out how many horses need to be made to break even:
300 ÷ 50 = 6
Answer:
I think it will be $16.50
Step-by-step explanation:
sorry if I'm wrong
F(1) = 8
Steps:
f(x) = 7(x-1) + 8
f(1) = 7(1-1) + 8
f(1) = 7(0) + 8
f(1) = 0 + 8
f(1) = 8
x = - 1
given 
= x + 3
square both sides
1 - 3x = (x + 3 )² ( expand right side using FOIL )
1 - 3x = x² + 6x + 9 ( subtract 1 - 3x from both sides )
0 = x² + 9x + 8
0 = ( x + 1)(x + 8)
equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = -1
x + 8 = 0 ⇒ x = - 8
As a check
substitute these values into the equation and if both sides are equal then they are the solutions
x = - 1 : 
= 2 and - 1 + 3 = 2 ← true
x = - 8 : 
= 5 and - 8 + 3 = -5 ← false
thus the only solution is x = - 1
