To calculate the cost of machining per clock, we need to divide the total cost of machining by the total number of clocks produced. From the given information, we know that each clock requires 2.5 hours of machine time to produce. Let's assume the cost of machining per hour is $x. Then, the cost of machining per clock would be:

Cost of machining per clock = (2.5 hours/clock) x ($x/hour) = $2.5x/clock

Now, we need to find the value of x. To do that, we need to know the total cost of machining. Unfortunately, the given information doesn't provide us with that. However, we do know that activity-based costing is used, which means that the total cost of machining is allocated based on the activities that go into producing each clock.

Without any additional information on activity-based costing or the allocation of costs, we can make a reasonable assumption that the cost of machining is the main driver of overhead costs for producing a clock. Therefore, we can estimate the total cost of machining as equal to the total cost of producing a clock minus the cost of materials:

Total cost of machining = Cost of producing a clock - Cost of materials

Total cost of machining = ($2.5x/clock) x (1 clock) = $2.5x

Total cost of producing a clock = Cost of materials + Total cost of machining
Total cost of producing a clock = $95 + $2.5x

Now, we can use the given information to set up an equation and solve for x:

Total cost of producing a clock = Cost of materials + Total cost of machining
$95 + $2.5x = Total cost of machining
$95 + $2.5x = $x

Solving for x, we get:

$x = $18

Therefore, the cost of machining per clock is $2.5x/clock = $2.5($18)/clock = $45/clock. Answer B is correct.
