5 litres of paint can cover a wall with an area of 75 square feet. How much paint would be needed to cover an area of 180 square feet?

Im pretty sure it’s the first one

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
