Neco 2025 Commerce Question 33

A company plans a 6‑month advertising campaign using TV spots and newspaper ads. Each TV spot costs \(\text{₦}150,000\) and reaches 120,000 viewers. Each full‑page newspaper ad costs \(\text{₦}80,000\) and reaches 90,000 readers. It is estimated that \(30\%\) of the TV audience also reads the newspaper, so the total unique reach is \(0.70\times120,000\) per TV spot plus \(90,000\) per newspaper ad. The campaign must achieve at least 1,200,000 unique individuals and the total advertising budget cannot exceed \(\text{₦}2,400,000\). Determine the numbers of TV spots and newspaper ads that satisfy both constraints while minimizing total cost, and give the minimum total cost.
