Answer:
c = (y-0.13y)(1.08)
Step-by-step explanation:
c = cost and y = the original price
The amount of money off is 13% of y, or 0.13 of y. You would subtract that from y to get the price of the cards with the discount. For final cost, you need the cost of the cards (1) plus the cost of tax (8%, or 0.08). 1+0.08 is 1.08, so that's what you would multiply y by to get the final cost of the cards.

interest= final investment - principal
interest / principal / annual interest rate = invested time

3.602 x 10 - 4
Multiply the numbers: 3.602 x 10 = 36.02
= 36.02 - 4
Subtract the numbers: 36.02 - 4 = 32.02!
= 32.02

Kim's age is twice of that of her sister. We'll let k2 = Kim and k = Kim's sister.
So, k2. When you add Kim's age to her sister age you get 36.
Because Kim is twice the age of her sister k2. And because it said 'add' then we put a + sign. k2 + s = 36. Now let's solve it.
k2 + k = 36 < Given
3k = 36 < Combine like terms
k = 12 < Divide both sides by 3
We know Kim's sister is 12 y/o but what about Kim herself? Earlier we assigned Kim to k2. Substitute 12 for k and you get 12(2) = 24
Kim's sister is 12 y/o and Kim is 24 y/o

Answer:
A(t) = 1.032^t
Ring rate grows faster
Annual rate of ring: 4.03%
Step-by-step explanation:
A(t) = (1 + 3.2%)^t
A(t) = (1.032)^t
Ring:
(1 + 0.33%)^(12t)
(1 + 0.0033)^(12t)
(1.0033¹²)^t
1.040326705^t
Increase of (1.040326705 - 1) × 100
= 4.0326705%
Faster rate: ring
