Ed bought a bottle of fancy mustard that holds 8.5 ounces. edputs about 1/25 of mustard on each hot dog he eats. how much of the mustard is left in the Boyle after he eats 7 hot dogs.

Total amt of mustard the bottle has = 8.5ounces

if edd puts 1/25 of the mustard on a hot dog ... 1/25 times 8.5 = 0.34ounes

if 0.34ounces of mustard is put on one hot dog

therefore 7 (0.34) is the amt put on 7 hot dogs

7 (0.34) = 2.38 ... (2.38 ounces is what is used)

to find what is left, we need to subtract what is used from the original amt in the bottle.

which is 8.5 - 2.38 = 6.12 ounces is left
