Rick rents a car from a company that charges him $25 per day plus 10 cents per mile driven. Which expression can represent the amount he owed on a recent rental?
Responses
A 25x + 0.1y25x + 0.1y
B 25.1x25.1x
C 25.1xy25.1xy
D 25.1 + 35y
A 25x + 0.1y expression can represent the amount Rick owed on a recent rental.
Is that correct
Apologies for the confusion. Yes, that expression is correct. The expression 25x + 0.1y represents the amount Rick owed based on the number of days he rented the car (x) and the number of miles he drove (y). The fixed cost of $25 per day is represented by 25x, and the variable cost of 10 cents per mile is represented by 0.1y.
In the equation, what is the value of x?
−4(x + 4x) = 2(2 − x) + 10

To solve the equation, let's simplify both sides:
−4(x + 4x) = 2(2 − x) + 10
−4(5x) = 4 − 2x + 10
-20x = 14 - 2x + 10
Next, let's combine like terms:
-20x = 24 - 2x
Now, let's isolate the x variable on one side:
-20x + 2x = 24
-18x = 24
To solve for x, let's divide both sides of the equation by -18:
x = 24 / -18
Simplifying further:
x = -4/3
Therefore, the value of x is -4/3.
Since none of the options provided include -4/3 as a choice, none of the options are correct.
is this true??
Apologies for the mistake in the previous response. Let's solve the equation correctly:
−4(x + 4x) = 2(2 − x) + 10
First, distribute the -4 and 2 to the terms inside the parentheses:
-4x - 16x = 4 - 2x + 10
Now, combine like terms:
-20x = 14 - 2x + 10
Simplify further:
-20x = 24 - 2x
Next, let's isolate the x variable:
-20x + 2x = 24
Simplify further:
-18x = 24
To solve for x, divide both sides of the equation by -18:
x = 24 / -18
Simplify the fraction:
x = -4/3
Therefore, the value of x is -4/3.
Since none of the options provided include -4/3 as a choice, none of the options are correct.
Sorry for the confusion earlier.
if the options was correct what would be the right answer
If one of the options provided was correct, we would choose that option as the right answer. However, none of the options provided (A, B, C, D) include the value of -4/3 as a choice. Therefore, we cannot determine the right answer based on the options provided.
