Independent variable = number of cars with domain 30 to 100 cars
Dependent variable = money raised with range $600 to $2000
The answer would be -15x+36. To solve this equation, you would first use distributive property and distribute the -9 to the values inside the parentheses (or multiply them). So, you would multiply -9 and x and -9 and -4 to get -9x+36-6x. Then, you combine like terms, which are -9x and -6x to get -15x. You can't simplify any further without knowing the value of x. Hope this helps!
Answer:

Below is the procedure that was used to find the answer.
Step-by-step explanation:
Let be "e" the weight in pounds of the elephant and "c" the weight in pounds of the cat.
According to the information provided in the exercise, we know that The weight of an elephant is
times the weight of a cat. Based on this we can write the following equation:

If the weight in pounds of the elephant is:

We must substitute this value into the equation and then solve for "c" in order to find the weight in pounds of the cat.
Then we get:

Answer:
8.25 pounds
Step-by-step explanation:
Its $3 per pound, so 24.75/3= 8.25
