F(x) = 20x+300
you sub in the x values (120 hours and 100 hours) for each equation
the only one they both work for is the last one
f(x) = 20x + 300
f(100) = (20 * 100) + 300 = 2000 + 300 = 2300
f(120) = (20 * 120) + 300 = 2400 + 300 = 2700
Answer:
More than
Step-by-step explanation
This year the club earned $20 more than twice what it earned last year. Let x represent the amount raised last year.

Since, x represents the earnings of last year, we can represent the earnings of this year as:
Twice of x + 20
