Question 120865
Nick has 7 more nickles than Dan has dimes. If Dan gives Nick 4 dimes, how much money will they have all together?
------------
Let Dan have "x" dimes.
Then Nick has "x+7" nickels
-----------------
If Dan gives Nick 4 dimes:
Dan will have "x-4"dime
Nick will have "x+7" nickels plus 4 dimes
-----------------------
Value:
Dan has 10(x+4) = 10x+40 cents
Nick will have 5(x+7)+10*4 = 5x+35+40 = 5x+75 cents
----------
Total money = 10x+40+5x+75 = 15x+115 cents
