<PRE><B>Question 347242</B>
Hi,
*Note:  Let x be the number of $5 bill for ex:
.
The question states the following to be true:
(76-x)would be the Number of $10 bill  and:
.
{{{5*x + 10(76-x) = 580}}}
.
Simplify and Solve for x
{{{5*x + 10*76-10x = 580}}}
{{{5*x + 760 -10x = 580}}}
{{{-5*x+ 760 = 580}}}
{{{180 = 5x}}}
{{{36= x}}}
.
36 $5s and 40 $10s
.
Check your answer:
5*36 + 10*40 = 580</PRE>
