Translate into an algebraic expression: n−1 increased by 110%

Part 1) The algebraic expression is equal to  or

Part 2) The algebraic expression is equal to

Step-by-step explanation:

Part 1) we have (n-1) increased by 110%

110%=110/100=1.10

so

The algebraic expression of (n-1) increased by 110% is equal to multiply 1.10 by (n-1)

Distributed

Part 2) we have n^(-1) increased by 110%

110%=110/100=1.10

so

The algebraic expression of n^(-1) increased by 110% is equal to multiply 1.10 by n^(-1)

Remember that

so

where are the choices?

the answer is 40.
