Step-by-step explanation:
You need to have 12 bills, and their values must add up to $170. Start with a guess, and adjust the guess until you find the answer.
The total number of $20 bills and $10 bills must be 10.
I made a table below. I started with a guess and kept adjusting it.

Answer:
-16
Step-by-step explanation:
Represent the number by n.
Then:
8(n + 18) = 16
Performing the indicated multiplication, we get:
8n + 144 = 16
Subtracting 144 from both sides results in 8n = -128.
Dividing both sides by 8: n = -128/8 = -16
The number was -16.
Step-by-step explanation:
g(x)= -16x² + 72x + 80
Plug 2 in to check if it's correct.
g(2)= -16(2)² + 72(2) + 80
-16(4)+128+80
-72+128+80
= 136
