Given the formulas below, I need assistance with correctly filling in the yellow blocks in the attached excel snip it and making sure that the two "total" cells' sum equals out to 38,558 as identified above the yellow cells.

Labor Revenues

Revenue (hrs.)= [Actual Labor (hrs.) - Budget Labor (hrs.)] x Budget Labor Rate ($/hr.)

Rate ($/hr.) = [Actual Labor Rate ($/hr.) - Budget Labor Rate ($/hr.)] x Budget Labor Costs (hrs.)

Costs (hrs.) = [Budget Labor Costs (hrs.) - Actual Labor Costs (hrs.)] x Actual Labor Costs ($/hr.)

Labor ($/hr.) = [Budget Labor Costs ($/hr.) - Actual Labor Costs ($/hr.)] x Budget Labor Costs (hrs.)
