Let hot dogs = X
So then soda would be 2x ( two times as much).
Now you have:
X + 2X = 162
Simplify:
3x = 162
Divide both sides by 3:
X =162 / 3
X = 54
2x = 54 *2 = 108
108 sodas and 54 hot dogs were sold.
1. x -3 = -34 will be the correct answer for 1

A. 1 to the right and 2 up from zero 1,2
B.1 to the left and two up from zero -1,2
C. 11 to the left and 2 up from zero -11,2
D. 11 to the right and 2 up from zero 11,2
Step-by-step explanation:
let x be the distance between the two points
A) -1.6 +x = 0.3
x = 0.3 + 1.6
x = 1.9
B) distance between two points = 1.9
Answer:
- D) y = 23(0.995)^x
- 85 years
Step-by-step explanation:
<h3>Part A</h3>
- Initial number of clients = 23
- Decrease rate = 0.5%
- Time = x years
<u>Required function:</u>
- y = 23(1 - 0.5/100)^x = 23(0.995)^x
<h3>Part B</h3>
y = 15, x = ?
- 15 = 23(0.995)^x
- (0.995)^x = 15/23
- (0.995)^x = 0.65217391304
- x log 0.995 = log 0.65217391304
- x = log 0.65217391304 / log 0.995
- x = 85 years
