Answer:
Shiloh initially invested $125, which grows annually at a rate of 2.5%.
Step-by-step explanation:
The balance in the account is given by the following exponential expression,
Exponential growth formula is
Where P is the initial amount invested
r is the rate of interest
When we compare the formula with given expression , we can see that we have 125 in the place of P
So initial amount invested is $125
Now we find out 'r'
1+ r = 1.025
Subtract 1 on both sides
r= 0.025
To get percentage we multiply by 100
0.025 * 100 = 2.5%
Shiloh initially invested $125, which grows annually at a rate of 2.5%.
Find a common denominator (in this case 8)
Multiply 4 to both numerator and denominator of -1/2
-1/2(4/4) = - 4/8
-7/8 - 4/8
Simplify. Combine terms
-7/8 - 4/8 = -11/8
Simplify. Change to mixed fraction
-11/8 = -8/8 - 3/8
-1 3/8 is your answer

Answer: The total cost of computer would be $719.95
Step-by-step explanation:
I use proportions for these types of problems so we begin with a proportion!
20/100=x/849
100x=16980
x=169.80
Then, after finding how much the discount is, we would subtract it.
849-169.80=679.20
Next, we would find the tax amount with another proportion to find what 6 percent of 679.20 is.
6/100=x/679.20
100x=4075.2
x=40.75
Lastly, we would add the tax, $40.75, plus the total after the discount, $679.20!
Hope this helps! Good luck! (:
