How do we represent the above facts in 1)axiom form and 2)clausal form

1) All babies are innocent 2) Anyone who is innocent and affectionate will be loved by others 3) Anyone who is loved by others, will receive gifts 4) Teena is an affectionate baby

My thoughts on the question : (Let Vx and Ex denote universal and existential quantifiers respectively )

Let B(x) denote x is a baby I(x) denote x is innocent A(x) denote x is affectionate L(x) denote x is loved by others G(x) denote x receives a gift

Axiom Form : 1) Vx[ B(x) --> I(x) ] 2) Vx[ I(x) ^ A(x) ] --> L(x) 3) Vx [ L(x) --> G(x) ] 4) B(Teena) --> A(Teena)

Have I done the first part correctly? And how do we do the second part?

Thanks!

I have math problem that I have fully solved but got stuck on two questions at the end. It asks me what is the sales person monthly commission if the commission is 15% and his monthly sales is 11,250.00. Next it asks what is the expense allowance if monthly sales is 1500.00 otherwise the expense allowance is 1500.00. Next it states if the team member monthly sales exceed 1,250.00. Do he receive a bonus? Yes Next it asks if total monthly sales is 86,250.00 (added monthly sales, commission,allowance,and bonus to get this amount)by the total monthly sales) Next it asks what is the total monthly compensation? ( I do not know how to find the compensation) Is is the total of all the numbers. This is where I am lost at the percentage and compensation.
