Your store cost on a loaf of bread is $0.75, and your retail price is $3.85. you are having a promotion which discounts the bread 20%. what is your margin on the discounted bread?

Given store cost on a loaf of bread is $0.75 and retail price is $3.85.

Discount is always given on retail price.

The amount of discount is 20%

Discount given on $3.85 = 20% of 3.85= .20(3.85)= 0.77.

Cost of bread after discount =3.85-0.77= 3.08

The discounted bread costs $3.08.

The difference in store cost and discounted cost = 3.08-0.75=$2.33

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
