Someone actually please help me thank you

Since a straight line will always be 180,
If you take 69+x=180 it will make this a lot easier
Simply rearrange it to get x=180-69 and you’ll get 111
Hope this helps

So don't take my word i'm not exactly a mathematical person but i would assume a. because while selling the soap every month you increase in sells so you would by 11 percent. the you would get the factor 0.89 which if i had to guess would be the monthly profit over 11 probably wrong tho
