The cost of a stove to a store owner was $500, and she sold the stove for $1080. What was her percent of profit based on cost?
Juliette [100K]

Answer:

116%

Step-by-step explanation:

Cost Price (C. P.) = $500

Selling Price (S. P.) = $1080

Profit = SP - CP = $1080 - $500 = $580

Profit percent

=  \frac{Profit}{CP}  \times 100 \\  \\  =  \frac{580}{500}  \times 100 \\  \\  =  \frac{580}{5}  \\  \\  = 116 \%

Varvara68 [4.7K]

Answer:

n = ( 40 - m )

Step-by-step explanation:

On a particular day, Ricardo drank a total of 40 fluid ounces of water.

If he drank m fluid ounces of water in the morning of that day, then the number of fluid ounces of water he drank the rest of the day is given by (40 - m) fluid ounces.

If n represents the number of fluid ounces water that he drank the rest of the day, then we can write the equation as  

n = ( 40 - m )

Therefore, the above equation can be used to find n. (Answer)
