ok so 68 customers everything morning times 7 days per week is 476 customer.
now we know that 476 x .67 = $318.92
she make 8.50 per week plus $318.92 from customers
now we have this equation of
500 = 8.5x + 318.92
find x you will know how many weeks she needs.
8.5x = 500 - 318.92
8.5x = 181.08
x = 181.08/ 8.5
x ~~ 21.3 weeks
It's a piece-wise. On the right side it's telling on the top one that infinity is less than or equal to 1. So draw a graph, and draw a line up vertically on X = 1. This will be your perimeter where nothing passes past that point. Then take the 1 and plug it in on the left. Your first function will be a horizontal line that goes across the Y axis at -1 but, you stop that line at the perimeter X= 1 that line you drew earlier. this will end in a close circle from the equal sign.
The same method can be used for the 2nd one where it says the 2nd function is infinite is more than 1. set your perimeter plus in 1 for x which gives you 1\3 + 1. start at 1 on the y axis of the perimeter and go up one over 3 (rise over run) this will end in a open circle from the greater or less than sign.
Answer-
I don't know what you want me to do with that, but I'll give you the equation and the answer of it:
Equation: 11 ≥ (4×n)-9
Answer: n could be five and below. For example, 5, 4, 3, 2, and 1 could work
Explanation-
If you take one of the numbers I used in the example and plugged it in, it would kinda look like this:
11 ≥ (4×4)-9
4×4=16
16-9=7
Since it said at most 11, this would be reasonable because 11 ≥ 7.
I’m pretty sure the answer is 6
The answer to the question is a
