The system of equations are:
a + l = 250 million equation 1.
a = 40 million + 2l equation 2
Where:
- a = profit made in Accra
- l = profit made in Lagos
The ratio of net return is 18 : 7
<h3>What is the profit made in the Lagos market?</h3>
Substitute for a in equation 1 using equation 2
40 + 2l + l = 250
40 + 3l = 250
3l = 250 - 40
3l = 210
l = 210 / 3
l = 70 million
<h3>What is the profit made in the Accra market?</h3>
Subtract 70 million from 250 million: 250 - 70 = $180 million
The ratio of returns : 180 million : 70 million
18 : 7
