Best ResponseYou've already chosen the best response.0You need to set up a system of equations here. As you're looking for the number of each kind of bill, we'll make a variable for each kind: let \(o\) be the number of ones, and \(t\) be the number of tens. First, we know that together they make \($6750\). Second, we know how many more ones there are then tens: \[ \begin{align} o + 10t = 6750\\ o + 150 = t\\ \end{align} \] Now all you need to do is solve the system for \(o\) and \(t\).
