Answer 2

Answer:

Replace key words with variables, numbers, and operations.

More than is addition, product is multiplication, and decreased by is subtraction.

The constants are 1, 7, and 5.

The expression is 1 + 7n – 5.

To evaluate the expression, substitute 6 in for the variable, and then use order of operations to simplify.

The value when n = 6 is 38.
