The answer is -15x + 6= -9x
5x - 25 + 3x + 9 = 180
8x - 16 = 180
8x = 196
x = 24.5
Answer:
Step-by-step explanation:
a. Yes, the following statement is true. The police officer is gathering data by writing down all the speeding tickets and seperating them into two categories, red and non-red cars. He can later analyze this data and compare them to determine whether or not his hypothesis is true.
b. The color of the car is the only variable that would not be a confounding variable in this scenario. This would instead be the independent variable and does not in any way affect the dependent variable which would be the number of speeding tickets received.
The equations that represent the salary that Chloe's receive under the different options are:
1) Option 1: $600
2) Option 2: $ 350 + 8% * x, where x is the sales.
Using the fact that 8% = 0.08
Option 2 = $350 + 0.08x
A) If she has $3200 weekly salary:
Option 1 gives $600 (it is a constant salary)
Option 2 gives: $350 + $ 0.08 (3200) = $350 + $256 = 606.
Then, she will earn more money with the option 2.
B) The equation that can be used to determine when she earns more is found by making the two options equal:
Optio 1 = Option 2 =>
600 = 350 + 0.08x
C) Option 1 wiil lead to a greater earn when 600 > 350 + 0.08x
=> 600 - 350 > 0.08x
=> 250 > 0.08x
=> (250 / 0.08) > x
=> 3,125 > x => x < 3,125
Then, the answer is that she will earn more money with option 1 when x < 3,125
