Answer:
a. 2.50:1
Step-by-step explanation:
Calculation for Current ratio 
First step is to Calculate the Total current assets : 
 
Cash $130,000 
Accounts receivables $100,000 
Inventory $110,000 
Prepaid insurance $60,000 
Total current assets (a) $400,000 
Second step is to Calculate the Total current liabilities : 
 
Accounts payable $140,000 
Salaries and wages payable $20,000 
Total current liabilities (b) $160,000 
 
Now let find the current ratio using this formula 
Current ratio = Total current assets / Total current liabilities 
Let plug in the formula 
Current ratio =$400,000 / $160,000 
Current ratio =2.50 : 1 
Therefore the Current ratio will be 2.50 : 1
