For problems like this, we need to find the pattern between the set of numbers to create a general equation for f(x). Given that x is the shipment number, let us first observe the first six shipments' behavior. 1 10 | 2 16 = 10 + 1(6) | 3 22 = 10 + 2(6) | 4 28 = 10 + 3(6)| 5 34 = 10 + 4(6) | 6 40 = 10 + 5(6) |
From these, we can observe that given x number of shipments, the total number of objects would be . Thus, given f(x), we have
