Q:
The Fan Cost Index (FCI) represents the cost of four average-price tickets, refreshments, and souvenirs to a sporting
event. The FCIs for an independent tennis league and an independent hockey league totaled \( \$ 127.94 \). The hockey FCI
was \( \$ 8.36 \) more than that of tennis. What were the FCIs for these sports?
The FCI for tennis was \( \$ \square \) and the FCI for hockey was \( \$ \square \).
