(5 * .35) + (x * .27) = 3.37 -- Setup the equation, 5 is the variety of apples, .35 is the fee for each, x is the variety of bananas, .27 is the fee of them, and 3.37 is the finished. a million.seventy 5 + (x * .27) = 3.37 -- This step you purely multiply out the 5 * .37 x* .27 = a million.sixty two (3.37- a million.sixty two) -- Now you subtract a million.seventy 5 from the two aspects. x = 6 (a million.sixty two/.27) --then you definately dive a million.sixty two via .27 and you get the respond 6. So the respond is 6 bananas.
