Answer:
39.75
Step-by-step explanation:
First, subtract 50 from both sides
200z + 50 - 50 = 8000 - 50
200z = 7950
Then isolate the variable by dividing both sides by 200
200z/200 = 7950/200
z=39.75

Answer:
He paid an of 4790
Step-by-step explanation:
If John took a loan of 18550
Then in 60 months, we will pay back 389 multiply by 60
389 × 60 = 23340
Therefore he paid an interest of 23340 minus 18550, that is
23340 - 18550 = 4790
