Answer:
=IF(A1<40000,(18%*I18),(27%*A1))
Step-by-step explanation:
The spreadsheet expression to be used is the "IF" function. The "IF" function is one that returns a value based on the conditions stated thereafter in the spreadsheet formula. Like every spreadsheet function, this also starts with =
In the question given,
The value to be examined is in cell A1. if A1 is less than $40000 is written as A1<40000, is true, the spreadsheets executes the next function stated as (18%*I18) otherwise (which in this case can be interpreted as A1 greater than or equal to $40000), compute the next command as shown above; (27%*A1)
The final parenthesis closes the command.
Hence the expression is IF(A1<40000,(18%*I18),(27%*A1)).
