Katrina drinks 0.5 gallons of water per day which expression shows how to find the number of cups of water she drinks in a week
kobusy [5.1K]

Answer:

56 cups of water

Step-by-step explanation:

Katrina drinks 0.5 gallons of water per day

We have 7 days in a week, hence, the number of gallons of water she drinks per week is calculated as:

1 day = 0.5 gallons

7 days = x

Cross Multiply

1 day × x = 7 days × 0.5 gallons

x = 7 days × 0.5 gallons/1 day

x = 3.5 gallons

Note that 16 cups = 1 gallon

The number of cups of water she drinks per week is

1 gallon = 16 cups

3.5 gallons = x

Cross Multiply

1 gallons × x = 3.5 gallons × 16 cups

x = 3.5 gallons × 16 cups/1 gallons

x = 56 cups

Therefore, Katrina drinks 56 cups of water in a week

a game cost $30 and a stoe bought it and sold it for $50. what is the percent makeup???????????????? need help ASAP!
PIT_PIT [208]

Answer:

67%

Step-by-step explanation:

Cost plus markup = selling price.

Here, the cost was $30 and the selling price was $50.  Subtracting $30 from $50, we get $20, which was the dollar amount of the markup.

We now compare this $20 to the original cost ($30):

$20

------- * 100^ = 67%

$30

The markup, as a percentage, was 67%.
