Well you could use the division sign
Answer: for 9 attendees it would cost $18
Step-by-step explanation: First you have to find the unit rate. So for every 7 attendees it costs $14, divide them both by the GCF which is 7. 14÷7=2
7÷7=1
So for every 1 attendee it is $2.
Now to figure out how much it would cost for 9 attendees, figure out what you have to do to 1 to get 9. Multiply it by 9.
And whatever you do to one number you have to do for the other. So $2 • 9 = $18
So for every 9 attendees it costs $18.
Meters and seconds.
Most short distance races involve meters and the timing is usually in seconds. She can use the information and convert it to miles per hour.
Calculate for the values of the terms by substituting 1 to n for 1991, 2 for 1992, 3 for 1993, and so on up to 9 for 1999.
We may opt to solve for the A for the 9 terms such as below.
n = 1.
A₁ = 0.17(1²) - 1.02(1) + 6.67 = 5.82
A₂ = 0.17(2²) - 1.02(2) + 6.67 = 5.31
A₃ = 0.17(3²) - 1.02(3) + 6.67 = 5.14
A₄ = 0.17(4²) - 1.02(4) + 6.67 = 5.31
A₅ = 0.17(5²) - 1.02(5) + 6.67 = 5.82
A₆ = 0.17(6²) - 1.02(6) + 6.67 = 6.67
A₇ = 0.17(7²) - 1.02(7) + 6.67 = 7.86
A₈ = 0.17(8²) - 1.02(8) + 6.67 = 9.39
A₉ = 0.17(9²) - 1.02(9) + 6.67 = 11.26
The sum of these values is $62.58. The answer is not among the choices.
1+1=2 1 equals one part the other 1 equals 2 parts 2 is the answer your welcome
