The total monthly income of Delisile including her spendings is R 1,520,000
<h3>How to find Delisile monthly income</h3>
Given:
- Amount spent on rent = 39% of x
= 0.30x
Amount remaining = x - 0.30x
= 0.70x
Amount spent on food and traveling = 50% of 0.70x
= 0.50 × 0.70x
= 0.35x
- Amount spent on education = R 220,000
Total = rent + food + education + amount left
x = 0.30x + 0.35x + 220,000 + 312,000
x = 0.65x + 532,000
x - 0.65x = 532,000
0.35x = 532,000
x = R 1,520,000
