A sports utility vehicle gets an average gas mileage of 17.5 miles per gallon. A hybrid version of this SUV averages 21.5 mpg. I
ZanzabumX [31]

Answer:

<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 ÷ \frac{17.5 miles}{gallon} = 13.54 gallons

2. Hybrid SUV = 237 miles ÷ \frac{21 miles}{gallon} = 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)

Determine the element, given the number of protons in an atom
LUCKY_DIMON [66]
You can determine an element based on its protons due to the atomic number.
Atomic number is the number of protons in an atom and you can locate it on your periodic table as the number above the letter. Each element has a different number of protons and because of that you can find the element on the periodic table based on its atomic number.
