Last year, there were 1,500 people who attended the homecoming football game at a local high school. This year, there is expected to be a 16% increase in attendance. What equation represents this scenario?

• f(x) = 1,500(11.6)^t

• f(x) = 1,500(0.116)^t

• f(x) = 1,500(116)^t

• f(x) = 1,500(1.16)^t

Solve for b:
4^{3b - 3} = 1/16

• 7
• -1/4
