So basically, you want to show why the two lines (m and n ) are the "same". To show this you would say <4 &<5 are also supplementary because it is the same as <3 & <6.

You have no profit. You have raised no funds, and lost $14.
(24% ÷ 100) × 8440= 2025.6

24% × 8440 = 2025.6 rounded to 2026
or 0.24 × 8440 = 2025.6 rounded to 2026
Do 100÷8, then whatever the answer is multiply it by 8 and ta da
