Answer:
Part A = 3 years
Part B = $3400
Step-by-step explanation:
To find this, we can model the value of the computer as V = A(.5)^x, in which x is the number of years. To find how long it takes to get to 12.5%, we can ignore all but the exponential part of the function and set equal to the percentage.
.125 = (.5)^x
3 = x
To find the initial value of the computer, use the formula created and solve for A.
V = A(.5)^x
425 = A(.5)^3
425 = A(.125)
3400 = A
1,700+.05(X-600)=2,100
-1700. -1700
.05(X-600)= 400
.05x-30 =400
+30=+30
.05x=. 430
Divided by .05
X=. 8,600
Answer:
Its c
Step-by-step explanation:
<span>The entire expression should be subtracted from 30. To subtract the quantity, distribute the negative sign, which changes the signs on the terms. So, the –2 changes to positive and gets added to 30 instead of subtracted from it.
Hope this helps! ^^</span>
