Vicky bought 312 pounds of oranges. Each pound costs $3.90. Which of the following equations represents the total cost, c , Vicky paid for the oranges and the amount of money she spent?(1 point) Responses 3.90c=3.5; Vicky paid $0.90. 3.90 c equals 3.5 ; Vicky paid $0.90. 3.903.5=c; Vicky paid $13.65. Start Fraction 3.90 over 3.5 End Fraction equals c ; Vicky paid $13.65. c3.5=3.90; Vicky paid $13.65. Start Fraction c over 3.5 End Fraction equals 3.90 ; Vicky paid $13.65. c3.90=3.5; Vicky paid $1.11.

The correct equation is 3.90c = 312. This equation represents the total cost, c, Vicky paid for the oranges and the amount of money she spent.
A culture of a certain bacteria doubles every hour. At 9:00 a.m, there were already 120 bacteria. Which equation represents the number of bacteria, n , at 8:00 a.m? How many bacteria were there?(1 point) Responses n2=120; at 8:00 a.m., there were 240 bacteria. Start Fraction n over 2 End Fraction equals 120 ; at 8:00 a.m., there were 240 bacteria. 2n=120; at 8:00 a.m., there were 60 bacteria. 2 n equals 120 ; at 8:00 a.m., there were 60 bacteria. n2=120; at 8:00 a.m., there were 60 bacteria. Start Fraction n over 2 End Fraction equals 120 ; at 8:00 a.m., there were 60 bacteria. 2n=120; at 8:00 a.m., there were 240 bacteria. 2 n equals 120 ; at 8:00 a.m., there were 240 bacteria.
The correct equation that represents the number of bacteria, n, at 8:00 a.m. is:
n = 120 / 2
This equation represents the fact that the number of bacteria doubles every hour. Simplifying the equation gives us:
n = 60
So, at 8:00 a.m., there were 60 bacteria.
The correct equation is: n = 60. None of the provided options match the correct equation.
n = 120 / 2
This equation represents the fact that the number of bacteria doubles every hour. Simplifying the equation gives us:
n = 60
So, at 8:00 a.m., there were 60 bacteria.
The correct equation is: n = 60. None of the provided options match the correct equation.

I apologize if my previous response was incorrect.
To find the number of bacteria at 8:00 a.m., we need to work backwards from 9:00 a.m., knowing that the bacteria doubles every hour.
To go from 9:00 a.m. to 8:00 a.m., we need to divide the number of bacteria by 2.
Given that there were 120 bacteria at 9:00 a.m., the equation representing the number of bacteria, n, at 8:00 a.m. would be:
n = 120 / 2
Simplifying this equation will give us the correct answer.
n = 60
So, at 8:00 a.m., there were 60 bacteria.
The correct equation is: n = 60.
