I think the 57 is an whole number.
So first we have to find out what the bottom number is so
8x+14
subsitute 8 for x
8(8)+14
64+14
78
so 156/78
an easy way to do this is to factor it out and find the 'ones' like 4/8=1/2 times 4/4 (4/4=1 and can be canceled out)
*=times
156=2*2*3*13
78=2*3*13
so (2*2*3*13)/(2*3*13)
2/1 times (2*3*13)/(2*3*13)
we can cross out the (2*3*13) and get
2 as the answer
I think it is $50.06.
I used a calculator for this.
Hope this helps! :)
Answer: A. The value of his investment decreased by 16% during this time period.
Step-by-step explanation:
Here the initial amount = n
Final amount after 1 years = 0.84n
The total change in the initial amount = n - 0.84n = 0.16 n

= 
Thus, the amount is decreases by 16% in one year,
⇒ Option A is correct.
