Here are the fuel efficiencies (in mpg) of 12 cars 43, 38,19, 16. 43, 33, 39, 48, 13, 28, 15, 37
What is the percentage of theses cars with a fuel efficiency less than 40mpg

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

The answer is d $21.65 i got that on a test in school before and got an a+ it should be d
