I keep getting 15,000U but it says the number is wrong.

The Baldwin Company, in its master budget for 2019, predicted total sales of $163,000, variable costs of $49,500, and fixed costs of $52,900 ($24,300 manufacturing and $28,600 nonmanufacturing). Actual sales revenue for 2019 turned out to be $151,000. Actual costs were as follows: variable, $54,300, and fixed, $51,500. What was the total master (static) budget variance for 2019? (Note that this variance is also referred to as the total operating income variance.) Was this total variance favorable (F) or unfavorable (U)? Total master (static) budget variance Unfavorable
