Answer:
x = 1
Step-by-step explanation:
Solve for x over the real numbers:
-1 + 2 + 1/x + 1/x = 3
-1 + 2 + 1/x + 1/x = 1 + 2/x:
1 + 2/x = 3
Bring 1 + 2/x together using the common denominator x:
(x + 2)/x = 3
Multiply both sides by x:
x + 2 = 3 x
Subtract 3 x + 2 from both sides:
-2 x = -2
Divide both sides by -2:
Answer: x = 1

Hope this helps :)
We are given the current market price that is <span>$1,200 and we are asked in the problem to compute the target cost if one wishes to gain a 30% profit. In this case, we have to minimize the cost to achieve the profit desired. Then,
1.3 y = 1200
where y is the target cost
y = $923.08
