The function f(x) is given as f(x) = 7x + 37, which means he earns $7 for each subscription sold and a base pay of $37 for the 5-hour shift. To determine how much he earns when he sells 15 subscriptions, we simply substitute x = 15 into the function: f(15) = 7(15) + 37 = $142. Therefore, the best choice is A.
