Last year a local restaurant realized sales of $270,000 with fixed costs of $110,000 and total variable costs of $80,000. a) What was the restaurants contribution rate (as a decimal) last year? Round to 2 decimal places. b) If the restaurant has the same contribution rate this year, what net income can be expected this year from a revenue of $170,000? Use the rounded answer from part (a) to solve this. Round to 2 decimal places. c) If the restaurant has the same fixed and variable costs this year, what sales this year will result in a profit of $37,000? Use the rounded answer from part (a) to solve this. Round to 2 decimal places. d) Suppose that the fixed costs this year rise to $120,000 and the variable costs remain the same. What is break-even revenue? Use the rounded answer from part (a) to solve this. Round to 2 decimal places. e) Suppose that the fixed costs remain at $110,000 this year but the variable costs fall to $71,000. What is the break-even revenue? Calulate a new contribution rate to solve this. Round to 2 decimal places.
