Answer:
x = 6
Step-by-step explanation:
8x + 2 + 70 + 60 = 180
8x + 132 = 180
8x = 48
x = 6
You would need to isolate the "X" variable because it is common in all 3 equations.
It would be: P * R * T /100
= 43800 * 4.8 * 2 /100
= 420480 / 100
= 4204.80
So, your final answer is $4204.80
Hope this helps!
