Final answer:
The student's question appears to require algebraic simplification, although it lacks clarity. A general method includes combining like terms and following the order of operations.
Step-by-step explanation:
The question seems to involve algebraic expressions and simplification. Without clear and complete information, it is challenging to provide a precise solution to the mathematics problem. However, taking a general approach to simplification, one would combine like terms, simplify expressions within parentheses, and follow the order of operations PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
For example, when you have an expression like 140 + 0.9(Y - 0.3Y) + 400 + 800 + 600 - 0.15Y, you would first combine like terms and simplify within the parentheses, resulting in 1940 + 0.48Y.
