Work Step by Step

You are given the following: Cost per hour of operating the aircraft = $2948$ $t$ = number of hours $2948t$ = total cost to operate the aircraft for $t$ hours You are supposed to find the total cost to operate the aircraft for 3.6 hours, so $t=3.6$. Since you already have an expression for the total cost given $t$, just plug in the value for $t$ and solve. $2948t=2948\times3.6=10612.80$ And remember your unit, which in this case is dollars.
