Answer:
--------------------
Mr. Tyson needs 50 bottles with 1/8 gallons of glue in each bottle.
He needs in total:
- 50 * 1/8 = 50/8 = 25/4 gallons of glue
He has in total:
- 7*(1/4) + 3*(1/2) + 1*(3/4) + 2*1 =
- 7/4 + 3/2 + 3/4 + 2 =
- 7/4 + 6/4 + 3/4 + 8/4 =
- (7 + 6 + 3 + 8)/4 =
- 24/4 gallons
He needs to add:
gallons more to fill the needed number of bottles
