If a is the number of events, then a = 1. Plugging in 1 for a in the equation
, you get
.
Total cost is $9.
Answer:
This equation is in standard form: ax 1+bx+c=0. Substitute 9 for a, 16 for b, and −112 for c in the quadratic formula 2a−b±b2−4ac.x= 2×9−16± 16^2−4×9(−112)Square 16.x=2×9−16±256−4×9(−112) Multiply −4 times 9.x=2×9−16± 256−36(−112) Multiply −36 times −112.x=2×9−16±256+4032 Add 256 to 4032.x=2×9−16±4288 Take the square root of 4288.x=2×9−16±8+67 Multiply 2 times 9x=18−16±8=67

Answer: 4x+40 dollars
Step-by-step explanation:
1. Define: since a ticket costs x dollars and 10$ for a drink and candy, your expression would be x+10 dollars.
2. Distrubute: Since there are 4 people, it would be:
4*(x+10)
3. Simplify: 4*(x+10) => 4x+40
Have a nice day! :D
