He rents the car for d days, but receives two days at no cost, meaning he only needs to pay for d - 2 days.
Each day's rental costs $45, so for d - 2 days, the cost is 45(d - 2). The total expenditure amounts to $315, leading to the equation
45(d - 2) = 315
Now, let's solve for d, the number of days rented.
45(d - 2) = 315
45d - 90 = 315
45d = 405
d = 9
He rented the car for 9 days.
Answer:
The expression representing the sum of three times a number and six, over the difference of seven times that number and nine
Step-by-step explanation:
we have

Let
p -----> the variable
we understand that
In the numerator we have (3p+6)
The statement that corresponds to this algebraic representation is "The sum of three times a number plus six"
The denominator is (7p-9)
The statement that corresponds to this algebraic representation is "The difference of seven times the number and nine"
therefore
The statement that represents this problem is "The sum of three times a number and six, divided by the difference of seven times the number and nine"

Step-by-step explanation:
To change the mixed number 83 1/3 into an improper fraction, we compute.
Thus, 83 1/3 converts to 250/3
Next, converting 250/3 into its decimal form gives us 83.33.
Our goal is now to determine 83.33 percent of 384.
We begin by performing the multiplication (83.33) with 384, yielding 83.33 * 384 = 31987.2
Subsequently, we divide by 100 to find the percentage.
Dividing 31987.2 by 100 shifts the decimal two places to the left, resulting in
31987.2/100 = 319.872
Consequently, 83 1/3 percent of 384 equals 319.872.
The correct choice is D). On the experiment's first day, five individuals received the email.
