 Question 499851: is this the same as the section as Applications of Linear Systems? Ex: A motel clerk counts his \$1 and \$10 bills at the end of the day. He finds that he has a total of 74 bills having a combined monetary value of \$326. Find the number of bills of each denomination that he has. let x= the number of \$1 bills the clerk has, and y= the number of \$10 bills he has He has 74 bills altogether, so one equation is x+y=74. To find the second equation, the dollar amount in \$1 bills plus the dollar amount in \$10 bills is \$326, so 1x+10y=326. Click here to see answer by rfer(12647)
