Question 1093106
<br>Let x be the number of $1 bills.<br>
Since the number of $5 bills is 2 more than the number of $1 bills, the number of $5 bills is x+2.<br>
The total number of $1 and $5 bills is now
{{{x + (x+2) = 2x+2}}}
and, since the total number of bills is 35, the number of $10 bills is
{{{35 - (2x+2) = 33-2x}}}<br>
Now you have expressions in terms of a single variable x for the numbers of $1, $5, and $10 bills.  Use those expressions to write an expression for the total value of all the bills -- $1 for each of the $1 bills, $5 for each of the $5 bills, and $10 for each of the $10 bills.  Finally, since you know the total value of all the bills is $228, write and solve the equation that says so.
{{{1(x) + 5(x+2) + 10(23-2x) = 228}}}<br>
I'll let you finish from there, to get some practice.
