Given:
A recipe combines 6 cups of nuts with 5 cups of granola.
John has 36 cups of nuts.
To find:
Number of cups of trail mix (total) does he have.
Solution:
The recipe combines 6 cups of nuts with 5 cups of granola.
The recipe combines 1 cup of nuts with cups of granola.
The recipe combines 36 cup of nuts with cups of granola.
So, the number of cups of granola in trail mix is
Total number of cups = cups of nuts + cups of granola.
Therefore, the total number of cups in trail mix (total) he have, is 66.

8) If you were charged $671 for renting a car, how many days did you rent the car for?
Answer:
7) C = 247 + 53d
8) 8 days
Step-by-step explanation:
7)
Let "C" represent the total cost of renting a car.
Let "d" represent the number of days the car is rented.
The equation to represent the total cost of renting a car for a certain number of days is:
C = 247 + 53d
8)
To find the number of days the car was rented when the total cost is $671, we can substitute the values into the equation and solve for "D."
671 = 247 + 53d
424 = 53d
d = 8
So, the car was rented for 8 days.
