The hamburger meat costed $36.13.
A = 1/4 * (pi) * d^2
A = 1/4 * (pi) * 8^2
A = 1/4 * (pi) * 64
A = 1/4(64) * (pi)
A = 64/4 * (pi)
A = 16 (pi) in^2
1 ≤ 3 - x
x + 1 ≤ 3 <em>added x to both sides</em>
x ≤ 2 <em>subtracted 1 from both sides</em>
Number line: ←----------------------·2 (fill in the dot at 2 since it is "equal to")

Answer: 
<u>Step-by-step explanation:</u>
The exponential growth formula is:
<em>NOTE: This problem is asking to use N instead of A and T instead of t</em>
Step 1: find the rate
Step 2: input the rate to find N
