Answer:
$432 favorable
Step-by-step explanation:
budgeted wages for 100 births = $2,380 + ($231 x 100) = $2,380 + $23,100 = $25,480
budgeted wages for 102 births = $2,380 + ($231 x 102) = $2,380 + $23,562 = $25,942
actual wages paid = $25,510
the spending variance = budgeted wages for 102 births - actual wages paid = $25,942 - $25,510 = $432 favorable
the activity variance = budgeted wages for 100 births - budgeted wages for 102 births = $25,480 - $25,942 = -$462 or $462 unfavorable
