Answer: 80% of 50 equals 40
hey so I really need help on this
Well, we know the eagle does 50 miles in 1hr, how long will it be for 125 miles?
well
![\bf \begin{array}{ccllll} miles&hours\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ 50&1\\ 125&x \end{array}\implies \cfrac{50}{125}=\cfrac{1}{x}\implies x=\cfrac{125\cdot 1}{50} \\\\\\ x=\cfrac{5}{2}](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccllll%7D%0Amiles%26hours%5C%5C%0A%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%26%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5C%5C%0A50%261%5C%5C%0A125%26x%0A%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B50%7D%7B125%7D%3D%5Ccfrac%7B1%7D%7Bx%7D%5Cimplies%20x%3D%5Ccfrac%7B125%5Ccdot%201%7D%7B50%7D%0A%5C%5C%5C%5C%5C%5C%0Ax%3D%5Ccfrac%7B5%7D%7B2%7D)
so, the eagle for 125miles does them in 5/2 hours or 2hrs and a half
now, how far will the sterling go in 2hrs and a half?
well, we know the sterling does 75 miles in 1hr
thus
![\bf \begin{array}{ccllll} miles&hours\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ 75&1\\ x&\frac{5}{2} \end{array}\implies \cfrac{75}{x}=\cfrac{1}{\frac{5}{2}}\implies \cfrac{75}{x}=\cfrac{2}{5}](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccllll%7D%0Amiles%26hours%5C%5C%0A%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%26%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5C%5C%0A75%261%5C%5C%0Ax%26%5Cfrac%7B5%7D%7B2%7D%0A%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B75%7D%7Bx%7D%3D%5Ccfrac%7B1%7D%7B%5Cfrac%7B5%7D%7B2%7D%7D%5Cimplies%20%5Ccfrac%7B75%7D%7Bx%7D%3D%5Ccfrac%7B2%7D%7B5%7D)
solve for "x"
I'm assuming your task is to write an expression for the verbal description you gave.
Subtract 10% of p from p. p - 0.10p
This is equivalent to 0.90p. If you don't pay 10%, you do pay 90%!
