Question 1208453
.
Mr Abbey bought 8 plates and 12 drinking cups from a shop. 
A plate cost him 5$ more than a drinking cup. If he spent 940$ altogether 
how much did a plate and a drinking cup cost
~~~~~~~~~~~~~~~~~


<pre>
Let "c" be the cost for a cup, in dollars..
Then the cost for a plate is (c+5) dollars.


Write an equation for total cost

    12c + 8*(c+5) = 940  dollars.


Simplify, solve and find "c"

    12c + 8c + 40 = 940,

    12c + 8c = 940 - 40,

       20c   =    900

         c   =    900/20 = 90/2 = 45.


<U>ANSWER</U>.  One cup costs $45.  One plate costs  $45 + $5 = $50.


<U>CHECK</U>.   12*45 + 8*50 = 940  dollars,  total cost.   ! correct !

Solved.
