You would do 2x-3+x+3x-15=360
combine like terms which then gives you
5x-18=360 then you would add 18 to both sides giving you
5x=378
and then you divide by 5 on both sides which will then give you your answer x=?

The best investment of the company is in southeast contract. The probability of profit of this contract is maximum 50% and of loss is minimum 20%.
<h3>What is probability?</h3>
Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
A company has an opportunity to bid on three contracts. Probability of profit and loss by all three contract is listed in the table below.
Contract profit, (P)* of profit, (P)* to break even loss, (P)* of loss
- Southeast $45,000, 50% 30% $6,000, 20%
- Southwest $60,000, 35% 40% $10,000, 25%
- California $112,000, 20% 40% $40,000, 40%
The company which will give the maximum profit probability and minimum loss probability will be the best investment.
In the above table, the southeast contract has the maximum probability of profit, which is 50% among all the contracts. Similarly, it has the lowest probability of loss, which is 20%.
Thus, the best investment of the company is in southeast contract. The probability of profit of this contract is maximum 50% and of loss is minimum 20%.
