Banana bought 3 companies for

A  :$20000000
B : $250000000
G : $350000000

He made a profit of $(9.6x10^6) when he sold the companies. He also made a profit of 25% on A and loss of 10% on B. Find the percentage profit he made on G.

How do I do this? What are the fixed steps? Thanks so much! :)))))

Let a,b,g be the cost of the companies

To make things simpler, let's deal in millions (10^6)

1.25a = 20
.9b = 250

a = 16
b = 277.77777

profit on a = 4
profit on b = -27.77777

profit on g = 9.6 -(4-27.777) = 33.3777

g = 350-33.3777 = 316.62222

%profit on g is profit/cost = .105 = 10.5%

If Catherine had $680 at the beginning od February,How much did she have at the end of January

To find the percentage profit Banana made on company G, let's follow these fixed steps:

1. Calculate the cost price (CP) of each company:
- Company A: $20,000,000
- Company B: $250,000,000
- Company G: $350,000,000

2. Calculate the selling price (SP) of each company:
Since Banana made a profit of $9.6x10^6 when selling the companies, we can calculate the selling prices:
- Company A: CP + Profit = $20,000,000 + $9.6x10^6 = $29.6x10^6
- Company B: CP + Profit = $250,000,000 - 10% of CP = $250,000,000 - ($250,000,000 * 10/100) = $225,000,000
- Company G: CP + Profit = $350,000,000 + Profit

3. Calculate the profit made on company A:
Profit A = SP A - CP A = $29.6x10^6 - $20,000,000

4. Calculate the profit made on company B:
Profit B = SP B - CP B = $225,000,000 - $250,000,000

5. Calculate the profit made on company G:
Since the cost price and selling price of company G are not given, we can use the fact that Banana made a total profit of $9.6x10^6 to calculate the profit made on company G.
Total Profit = Profit A + Profit B + Profit G
$9.6x10^6 = Profit A + Profit B + Profit G

Rearrange the equation to solve for Profit G:
Profit G = Total Profit - (Profit A + Profit B)

6. Calculate the percentage profit made on company G:
Percentage Profit G = (Profit G / CP G) * 100

Now, let's substitute the values and calculate the percentage profit Banana made on company G.
