Formulate the situation as a system of two linear equations in
two variables. Be sure to state clearly the meaning of your
x- and y-variables. Solve the system by the
elimination method. Be sure to state your final answer in terms of
the original question.
A lawyer has found 60 investors for a limited partnership to
purchase an inner-city apartment building, with each contributing
either $6,000 or $12,000. If the partnership raised $528,000, then
how many investors contributed $6,000 and how many contributed
$12,000?
| x | = | $6,000 investors |
| y | = | $12,000 investors |
