The equation 10x+12=$72.00 shows the total cost for x people attending a concert. How many people attended the concert.
A. 4 people
B. 5 people
C. 6 people
D. 8 people
We can solve for x by isolating it on one side of the equation:
10x + 12 = 72
10x = 60
x = 6
Therefore, the answer is C. 6 people attended the concert.
To find the number of people that attended the concert, we need to solve the equation 10x + 12 = $72.00.
Step 1: Subtract 12 from both sides of the equation:
10x = $72.00 - $12.00
10x = $60.00
Step 2: Divide both sides of the equation by 10 to isolate the variable x:
x = $60.00 / 10
x = 6
Therefore, the number of people that attended the concert is 6 people.
So, the answer is C. 6 people.
To find out how many people attended the concert, we need to solve the equation 10x + 12 = $72.00 where x represents the number of people attending.
To solve for x, we'll follow these steps:
1. Start by subtracting 12 from both sides of the equation: 10x = $72.00 - $12.00 = $60.00
2. Divide both sides of the equation by 10 to isolate the x term: (10x)/10 = $60.00/10
3. Simplify: x = $6.00
So, based on the equation, 6 people attended the concert. Therefore, the correct answer is:
C. 6 people
