The answer to this question is the letter "A" which is $20.70. The solution is shown below:
If the guy will solely use the car, his expenses for the gasoline per month is:
Guy alone = $ 2.76/gallon * 15 gallons = $ 41.4
If the guy will let his two officemates ride the car and contribute each quarter of the of a tank:
First officemate = 15/4 * $2.76 = $ 10.35
Second officemate = 15/4 * $2.76 = $10.35
The guy total savings is shown below:
Total savings = $41.4 - $10.35 -$10.35
Total savings = $20.70
The answer is the letter "A".
For problems like this you can move the y's on the bottem up top by fliping the sign of the exponent (in this case 7 to -7) and MULTIPLYING it with EVERYTHING on top, then because of properties of multplication you can add the exponents to combine them into one term (in this case add 3 and -7 to get -4)
If any of this does not make sense let me know and ill try to clarify better
Absolute value is just how many integers rhat number is away from 0. i say this because it’s not too hard of a thing to learn and it’s very important in the higher grades.
3 is 2 6/7
5 is a greater than symbol >
7 is 1/3 and negative 1/3 so -1/3
8 is 14 and -14
9 is 21 and -21
11 is | -75 |
i’m not sure about 13 but i believe it could be | -8 |
i hope this helped
