ok this is really confusing me


1. Leo held a garade sale. He priced all the items at a dim or a quarter. His sales totaled $23.95 for 139 coins. How many dimes and quarters did he have?

  • Algebra -

    your supposed to solve my graphine. subsitution or elimination

  • Algebra -

    d dimes and q quarters
    d+q = 139
    10 d + 25 q = 2395

    I would solve the first equation for d = (139 - q)
    then substitute that value for d in the second equation

    however you could just as well multiply the first equation, both sides, all terms, by ten. the if you subtract the first equation from the second, you eliminate d.
