<PRE><B>Question 103049</B>
assign a variable for one of the coins and find the other coins in relation to it


let x=quarters, 2x=nickels, x+2=dimes, 40-(x+2x+(x+2))=pennies
...there are 40 coins, so the pennies are 40 minus everything else


multiply the coins by their value and add to find the total value
...working in cents to avoid the decimals may be easier


25(x)+5(2x)+10(x+2)+1(40-(4x+2))=386 ... 25x+10x+10x+20+40-4x-2=386


41x+58=386 ... 41x=328 ... x=8 ... 2x=16 ... x+2=10 ... 40-34=6</PRE>
