Let's make an equation.
C = 5.20(24) + 50
C being the cost we have to figure out,
5.20 being the charge per hour(which we multiply to 24 because we need the charge for 24 hours),
and 50 being the fee we need to add to our cost.
In order to solve for C, we need to first multiply 5.20 with 24.
5.20 * 24 = 124.80
Now we need to add our $50 fee
124.80 + 50 = 174.80
Therefore, it would cost $174.80 to rent equipment for 24 hours :)
