Answer:
The second option will cost her less than the first one.
Step-by-step explanation:
In order to solve this problem we will create two functions to represent the cost of the car in function of the miles drove by her.
For the first option we have:
For the second option we have:
Since she intends to drive it for 10,000 miles per year for 6 years, then the total mileage she intends to drive her car is 60,000 miles. Applying this to the formula of each car and we have:
The second option will cost her less than the first one.
Answer:
$26.80
Step-by-step explanation:
(I don't know exactly how other people were taught to do percentages, but this is how I was taught and I find it the easiest for me.)
You are going to subtract your percentage number by 100.
100 - 33 = 67
This will give you your multiplier so you can then get your answer but you have to turn it into a decimal.
0.67 x 40 = 26.80
Can you post the answer choices please ??
Since they are similar, you need to find the ratio of similarity (I made up the term, there is probably a correct one that I can’t remember).
If you divide 16/40, you’ll find that that ratio is 2.5. So then you just multiply 16 x 2.5. You’ll get 18.
18 is the length of the top of the trapezoid.
You set 18=2x+4 and solve it algebraically. Subtract 4 from both sides.
14=2x
Divide by 2 and x=7
(You can also check that the ratio is right by 16/18 is the same decimal value as 40/45. You’ll get .88888...)
