need help solving 1 and 2 (a and b for 2)

i wrote the formulas down

1. What is the required number of customers to satisfy the following conditions? fixed cost =$118,000, profit goal =$9,000, average check =$59.25, average variable cost per customer =$12.5 \# of units= (FC+OI)/Price-VC per unit 2. A 100-seat restaurant with average daily turnover of 2 and average check of $15 opens 365 days a year. Food cost is 38% of revenue and other variable costs is 22% of the revenue. Fixed costs, including the owner's salary (withdrawals), are $220,000 a year. a. The owner wants to increase the operating income to $250,000 and add $20,000 to her own salary. She decided to achieve this by increasing the average check to $17 and spending an additional $30,000 on advertising Assuming the variable costs per customer does not change, what is the required number of customers to achieve this goal? Hint: Use the original price $15 to find the VC per customer. This VC per customer does not change so use the new price $17 and this original VC per customer to find the new contribution margin per customer. VC/unit=Price*VR b. What is the seat turnover for the required number of customers
