Meredith works at a blood bank. She needs to write a report of the ratio of type- a blood donated to tpye-o blood donated, but she lost this month's logs that had the quantities. She knows that last month 25 pints of tpye-a blood were donated and 42 pints of tpye-o blood were donated. She remebers that this month 55 pints of tpye-a blood were donated. if the ratio held true for this month, how can Meredith determine the amount of tpye-o blood donated
