Answer:
total overhead costs = $7,793.90
Explanation:
the overall budget is missing, so I looked for a similar question:
the total budgeted overhead costs must include the variable overhead costs plus the fixed overhead costs:
variable overhead costs = [($234 + $315)/90] x 99 = $603.90
fixed overhead costs = $220 + $4,290 + $2,680 = $7,190
total overhead costs = $7,793.90
