Answer:

D. 0.8p(1p-0.2p)

Step-by-step explanation:

If p is the original price, the markdown price is:

p - 20% =
p - p(20/100) =
p - 0.2p =
0.8p

Now, another 20% off:

0.8p - 20% =
0.8p - 0.8p(20/100) =
0.8(p - 0.2p) =
0.64p

Answer choices:

A. 0.2(1p-0.2p)
B. 0.6p
C. (1p-0.2p)-0.2p
D. 0.8p(1p-0.2p)

Correct one is D

Ms.Wright opens a savings account with a deposit of $800. The bank will pay her 3% interest per year A.) how much interest will

Norma-Jean [14]

A) Ms.Wright receive $12 as interest at the end of 1/2 year.

B) Ms.Wright receive $24 as interest at the end of 1 year.

Step-by-step explanation:

The sum deposited in the bank = Principle = $800

The rate of simple interest = 3%

The time = 6 months = (6/12) years = 0.5 years

$\textrm{SIMPLE INTEREST} = \frac{P \times R \times t}{100} \\\implies SI = \frac{800 \times 3 \times 0.5}{100} = 12$

So, here simple interest = $12.

So Ms.Wright receive $12 as interest at the end of 1/2 year.

B) Now here Time = 1 year

so, Simple interest = $\frac{800 \times 3 \times1 }{100} = 24$

So Ms.Wright receive $24 as interest at the end of 1 year.
