my, Dan, and Mike are competing in a cooking competition. They all used different amounts of milk from a container holding 6 gallons of milk.
Amy used 13% of the total milk in the container.
Dan used 0.14 of the total milk in the container.
Mike used 0.5 gallon of the total milk in the container.
Who used the greatest amount of milk from the container? Show your work and explain your answer in words.

Answer 1

18 - 4.25 = 13.75.
13.75 - 9.75 = what is left to spend, $4.00

This means she can buy no more than 8 cracker packs.

Answer 2

Answer:

Part A:

Let the number of packs of crackers Fiona can buy be = x

In total Fiona has = $18

As per situation inequality forms:

$4.25+9.75+0.5x \leq18$

$0.5x \leq4$

$x \leq8$

So, Fiona can buy at most 8 packs of crackers.

Part B:

Total milk = 6 gallons

Amy used 13% of the total milk in the container.

This becomes: $0.13\times6=0.78$ gallons.

Dan used 0.14 of the total milk in the container.

This becomes: $0.14\times6=0.84$ gallons

Mike used 0.50 gallon of the total milk in the container.

Comparing all we get Dan used the greatest amount of milk from the container.
