Answer:
fourth and fifth
Step-by-step explanation:
If George gets a 20% raise, that means he will now earn
$445 + $445*20% = $445 + $445*0.2 = $445*1 + $445*0.2 = $445*(1 + 0.2) = $445 * 1.2
So we know the fourth is correct.
We also know that current pay is 100% of current pay and the new pay will be 120% of current pay, so x/455 must be equal to 120% / 100% which is equal to 120/100, so fifth is correct too.

Answer:
A. Her expenses are $25 per week.
Step-by-step explanation:
Using a linear function f(x) = mx + b, m= slope and b = y-intercept or initial value. With the values of the given function: E(x) = 7x - 25, we can determine that the overall earnings (E(x)) is based on a profit of $7 per door ('x') and that if Jessica is subtracting $25 from her earnings, that this must be the cost per week for her expenses. So, she would need to knock on a minimum of 4 doors each week in order to make a profit.
