The players of a travel volleyball team have no more than a combined total of 385 shirts and

hats to sell for a fundraiser to fund a trip.

• The shirts sell for $12 each, and the hats sell for $25 each.

• The players must make a combined total of at least $7, 450 from the fundraiser.

If s represents the number of shirts sold during the fundraiser, and h represents the number of hats sold during the fundraiser, which system of inequalities represents the scenario?

• 12s + 25h ≤ 385

  s + h ≤ 7,450

• 12s + 25h ≥ 385

  s + h ≤ 7,450

• 12s + 25h ≤ 7,450

  s + h ≤ 385

• 12s + 25h ≥ 7,450

  s + h ≤ 385

Workers at two organizations use different approaches to placing phone calls represented by f(x) and g(x).

• The number of phone calls at Organization 1, where workers place a constant number of phone calls per hour, is represented by f(x).

• The number of phone calls at Organization 2, where workers use a phone tree and each person called in turn calls others, is represented by g(x).

Consider the graph of functions f(x) and g(x), representing the total number of phone calls over time at each organization, x, in hours.

Which statement is true?

• f(10) = g(10)

• f(10) < g(10)

• f(10) > g(10)

• The values of the functions cannot be compared.

The manager of a start-up company hires 16 employees in the year 2019 and hires an average of 25% more employees each following year. The input-output table shows two values of a geometric sequence, where the input represents the time, in years, since 2019, and the output represents the average number of employees hired.

Which function, f(n), models the situation, where n represents an integer greater than 0?
