6,395.00 x 2 = 12,790
So $12,790 for the emerald rings.
5,314.00 x 2 = 10,628
So $10,628 for the pearl bracelets.
12,790 + 10,628 = 23,418
So $23,418.00 for all four pieces of jewelry.
Hope it helps!
Answer:

Step-by-step explanation:
comment if u need explanation :))
We need to use the formula for simple interest which is
I= prt
Where I is the amount of money you earned or pay in interest
p is the principal, the amount you deposited or borrowed
r is the interest rate expressed as a decimal
t is time in terms of years
In this problem, I= 1,680
p= 3000
t= 8
'. r is what we are looking for.
Substituting the numbers into the simple interest formula, we get
I=. p r t
1,680=(3000)(r)(8). Multiplying
1,680= 24,000r Divide both sides by 24,000
0.07= r
So, the percentage is (0.07)(100)= 7%...
3000000...........
10^6 =1000000 (3) = 3000000
Answer:
6.48%
Step-by-step explanation:

t = 31.93
c = 29.99
b = 31.93 - 29.99
b = 6.48%
