Thus,

Multiply 4 by nine and for by six
hope this helped
Step-by-step explanation:
Here's the first question and how to solve the second.
So the first business start with 250, that's your b in slope.
y = mx + b
y = mx + 250
Now, they charge 14 an hour so that's your m.
y = 14x + 250
x is the number of hours it takes.
The second business is straight up 22 per hour, so it's just y = mx, where b is 0.
y = 22x VS y = 14x + 250
Try plugging in different numbers and seeing how much it take to level out!
<u>Answer:</u>
The answer is $249.60
<u>Step-by-step explanation:</u>
This is a simple question. Firstly you will take the total cost and multiply it by 0.22. The answer to this is 70.4. Take that and subtract it from the total cost because 70 is the discount price. Once subtracted you will get 249.6. In conclusion, the sale price of the item is $249.60.
