In Paul’s bicycle shop, 50 bicycles were inspected. If 20 needed new tires and 30 needed gear repairs, answer the following. a) What is the greatest number of bikes that could have needed both? b) What is the least number of bikes that could have needed both? c) What is the greatest number of bikes that could have needed neither?

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this

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
