Answer:
$37.5+$3r
Step-by-step explanation:
We can assume that the number of rides is r. Since each ride is $3.00, all rides are $3r ($3xr).
We also know that there are <u><em>FIVE </em></u>people going to the fair, with Tory being one and each of her friends. Since the entrance fee is 7.50, we can do 7.50x5 which is $37.5.
Then, you can add it which is $37.5+$3r
If you divide 600/ 45 mins you get the kilometers per minute which is 13.33. Then you multiply 13.33 times 30 mins and you get 399.9 or 400 kilometers
I prefer adding polynomials horizontally because its quick to just group and add like terms. Plus you read things horizontally so it seems more natural. if you add them vertically you have to line up the like terms and place a zero where there are none.
Horizontal
5x³ + 2x² + 6 + x³ - 6x² + 3x - 4 = 6x³ - 4x² + 3x + 2
Vertical
5x³ + 2x² + 0 + 6
+ x³ - 6x² + 3x - 4
------------------------
6x³ - 4x² + 3x + 2
