I am really stuck with this part and wondering if someone could help me with it.

Based on the CVP analysis of 2020:

Determine 1) the required sales dollars to achieve an annual operation income like 2016.

2)the required sales dollars to achieve an annual net income after taxes of $180,000. (Cooperate income tax rate is 25%)

3) The required sales in dollars to achieve an annual profit of 320,000 after taxes and after paying 12% of the operating income before taxes as a bonus. (Cooperate income tax rate is 25%)
