ANSWER:
The profit made by Leila is $28.
SOLUTION:
Given, Leila and Jo are two partners in a business.
Leila makes $4 in profits for every $5 that Jo makes.
Their total profit on the first item sold is $63,
We have to find how much profit does Leila make?
Let the profit made by Leila be n, then profit made by Jo will be 63 – n.
We know that, if Leila makes 4 ⇔ Jo makes 5
And, if Leila makes n ⇔ Jo makes 63 – n
Now by chris cross method. 4 x (63 – n) = n x 5
4 x 63 – 4n = 5n
5n + 4n = 4 x 63
9n = 4 x 9 x 7
n = 4 x 7 = 28.
Hence, profit made by Leila is $28.
