1-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 $3,000 or $6,000. If the partnership raised $267,000, then how many investors contributed $3,000 and how many contributed $6,000?
x =___________ $3,000 investors
y = ___________$6,000 investors

3-Express the situation as a system of two equations in two
variables. Be sure to state clearly the meaning of your x-
and y-variables. Solve the system by row-reducing the
corresponding augmented matrix. State your final answer in terms of
the original question.
For the final days before the election, the campaign manager has a
total of $48,000 to spend on TV and radio campaign advertisements.
Each TV ad costs $3000 and is seen by 10,000 voters, while each
radio ad costs $500 and is heard by 2000 voters. Ignoring repeated
exposures to the same voter, how many TV and radio ads will contact
168,000 voters using the allocated funds?
x | = | TV ads |
y | = | radio ads |
