The total number of tulips that the florist had was 39.
Total number of roses and tulips together = 76
Total number of roses = 37
Therefore, to find the total number of tulips we need to subtract the total number of roses from the total number of flowers together.
Hence, the total number of tulips = 76 - 37 = 39
Thus the total number of tulips that the florist had was 39.
