Given the equation for determining the cost expressed as:
C = 8p + 12 where:
p is the number of people attending a basketball game
To determine the number of people that could attend for a cost of 100 dollars, we will substiute C = 100 into the equation and calculate the value of p as shown:
C = 8p+12
100 = 8p+12
subtract 12 from both sides
100-12 = 8p+12-12
88 = 8p
8p = 88
Divide both sdes by 8:
8p/8 = 88/8
p = 11
Hence the number of people that can attend for a cost of 100 dollars is 11 people
