Answer:
60 miles.
Step-by-step explanation:
Given:
We rent a car for the day and are offered two payment options.
With option A we pay $25 flat rate plus $0.15 per mile.
With option B we pay a $10 flat rate plus $0.40 per mile.
Question asked:
For what amount of miles would the cost of option A be equal to option B ?
Solution:
<u>Let amount of miles for which the cost of option A be equal to option B = </u><u />
For option A, we pay =
For option B, we pay =
Now, to find amount of miles for which the cost of option A be equal to option B, we will equalize the equation to find the value of
By subtracting both sides by 10
By subtracting both sides by
By dividing both sides by
Therefore, for 60 miles, the cost of option A will be equal to option B.
Answer: there are 200 nickels in 1 kilogram of nickels
Step-by-step explanation:
For this case we must take into account the following conversion:
1Kg = 1000 g
Therefore, we can make the following rule of three:
5 grams ---------> 1 nickel
1000 grams ----> x
Clearing x we have:
x = (1000/5) * (1)
x = 200 nickels
