Hi. Are you a math student? This looks like a beginning algebra exercise involving a system of two linear equations. Two common solution methods are "Substitution" and "Elimination". If you don't have a textbook, let us know.

The first step is to assign a variable name for each of the two unknown amounts you've been asked to find. If you've already done that part, please share.

:)
