There were 610 people at a play. The admission price was $3.00 for adults and $1.00 for children. The admission receipts were $1,250.00. How many adults and children attended?

  • math 140 -

    a + c = 610, therefore c = 610 - a

    3a + c = 1250

    Substitute 610-a for c in second equation and solve for a. Insert that value into the first equation and solve for c. Check by inserting both values into the second equation.

    290 children---- 290X 1.00= 290
    320 adults ----- 320X 3.oo= 960
    therefore 290+ 960= 1250
