<h2>The answer is $6.52.</h2>Explanation:
Firstly, let's check out the given:
1. Sports Utility Vehicle's (Original SUV) avg gas mileage - 17.5 miles per gallon (mpg)
2. SUV's (Hybrid SUV) avg gas mileage - 21.5 miles per gallon (mpg)
3. Gas price - $2.59 per gallon
What is asked? How much would you save driving 237 miles in the hybrid SUV compared to the original SUV?
Next, you have to know how much gallons each car consumes upon driving 237 miles. You can do division in this step.
1. Original SUV = 237 miles ÷ = 13.54 gallons
2. Hybrid SUV = 237 miles ÷ = 11.02 gallons
Now that you know how much gallons each car consumes, you can now get the gas price for the gallons.
1. Original SUV = 13.54 gallons × $2.59 per gallon = $35.06
2. Hybrid SUV = 11.02 gallons × $2.59 per gallon = $28.54
In order to check the difference, you have to subtract.
- $35.06 - $28.54 = $6.52 (this is the amount of money that you can save driving 237 miles in the hybrid SUV compared with the original SUV)
Explanation:
Volume of the stock solution is = ?
Initial concentration of ampicillin is = 100 mg/ml
Final volume () = 30 ml
Final concentration of ampicillin () = 25 mg/ml
Therefore, calculate the volume of given stock as follows.
=
Now, putting the given values into the above formula as follows.
=
=
= 7.5 ml
Now, we will calculate the volume of water added into it as follows.
Volume of water added =
= 30 ml - 7.5 ml
= 22.5 ml
Thus, we can conclude that required solution is 22.5 ml of deionized water.
