Answer:

Step-by-step explanation:
Since interest is compounded semi-annually (half a year or 6 months), in a spawn of 2 years, the interest will have been compounded 4 times. As given in the problem, each time the interest is compounded, the new balance will be 107% or 1.07 times the amount of the old balance.
Therefore, we can set up the following equation to find the new balance after 2 years:

Answer:
x< -1/4
Step-by-step explanation:
- 3/5 x + 1/5 > 7/20
Subtract 1/5 from each side
- 3/5 x + 1/5-1/5 > 7/20-1/5
-3/5x > 7/20 -1/5
Get a common denominator
-3/5x > 7/20 -1/5*4/4
-3/5x > 7/20 -4/20
-3/5x> 3/20
Multiply by -5/3 to isolate x
Remember that flips the inequality
-5/3* -3/5 x < 3/20*-5/3
x < -1/4

a computer is an electronic device,which input data/instruction,store and processes it and produces output in the desired from
We'll do it in cents and convert when we have to.
Tanya paid x per item, a total of 4x.
Tony paid x-125 per item (in cents) for a total of 5(x-125)
4x = 5(x-125)
4x = 5x - 625
x = 625 = $6.25
Check:
4(625) = 2500
5(625-125)=2500, same, checks
Answer: Tanya paid $6.25 per item, Tony $5.00 per item
