Question

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

Answer 1

I got that he is left with `6.1` ounces of mustard after having the `7` hot dogs.

Explanation:

He uses:
`1/25xx8.5=0.34` ounces of mustard on each hot dog;

For the total of `7` hot dogs he will use:

`7xx0.34=2.38~~2.4` ounces in total.

He will then have left:

`8.5-2.4=6.1` ounces of mustard.
