Mrs. Rodrigues was selling two kinds of raffle tickets for $1.50 and $3.50. The number of $1.50 tickets sold was 5 more than three times the number of $3.50 tickets sold. She earned a total of $1,607.50. How many $1.50 tickets were sold?

3 answers

Let x = # of 1.50 and y = # of 3.50

x = 3y + 5

1.50x + 3.50y = 1607.50

Substitute 3y+5 for x in the second equation and solve for y. Insert that value into the first equation and solve for x. Check by putting both values into the second equation.
