Neco 2020 Commerce Question 46

A company plans to run TV and newspaper advertising. A 30‑second TV spot costs \(\text{₦}150\) and reaches 12,000 viewers. A full‑page newspaper ad costs \(\text{₦}200\) and reaches 8,000 readers. The total advertising budget is \(\text{₦}5,000\). If more than 20 TV spots are purchased, each additional spot costs 10% less (i.e., \(\text{₦}135\) per spot). If more than 10 newspaper ads are purchased, each additional ad costs 5% less (i.e., \(\text{₦}190\) per ad). The company may purchase at most 30 TV spots and at most 15 newspaper ads. Determine the numbers of TV spots and newspaper ads that give the maximum total audience reach without exceeding the budget, and state that maximum reach.
