Answer:
Percent of decrease - the ratio of an amount of decrease to the previous amount expressed as a percent
Step-by-step explanation:

where t is the number of hours worked by Natalle
Here, we want to write an equation that will represent the given scenario
Let the number of hours for which she earned the pay be t
From the question, she earns $11 per hour
So for t hours, the amount earned excluding the tip will be;

Now, let us add the tip and equate to the total amount earned
We have this as;
1) 343
7 • 7 • 7 = 343
2) 64
2 • 2 • 2 • 2 • 2 • 2 = 64
3) 256
4 • 4 • 4 • 4 = 256
You can either multiply both equation by -2 or multiply both equations by 3 because when you multiply -2 you can eliminate x term
1. -2(x) -2(y) = -2(1) -> -2x -2y=-2
So far
-2x-2y=-2
+
2x-3y= -30
(-2x+2x) + (-2y-3y)= -32
0-5y = -32
Y= 32/5
Substitute y with 32/5
X+ 32/5= 1
Minus -32/5 over
X= -27/5
I don’t know why my answer doesn’t match with those answers above. I also checked by calculator. Did you write the question wrong?
6*16 equals 96, 96 - 37 = 59, 59 is the answer
