Your friend tells you that if you let her keep 2020 of your Pokemon cards for three months, she will give you 22 cards extra whe

Dmitrij [34]

Answer: 40 %

Step-by-step explanation:

Let the amount of one card = x

Hence, the value of 20 cards ( Principal amount ) = 20x

And, the value of 22 cards ( Total amount after 3 month ) = 22x

⇒ Total interest in 3 month = 22x - 20x =2x

Let the annual interest rate = r %

$\frac{20x\times r\times 3/12}{100}=2 x$ ( By the formula of simple interest rate )

$\implies \frac{10\times r\times 1/4}{100}=1$

$\implies \frac{10r}{400}=1$

$\implies 10r=400$

$\implies r=40\%$

Hence, the annual rate of interest = 40%

(4^p*4^1)^3 simplifies to 4^15 what does p equal?

zzz [600]

When an exponent is outside the parentheses, you "distribute" it to the other exponents inside the parentheses.

(4^p)^3 would become 4^3p

(4^1)^3 would become 4^3

When the bases are the same, you just simply add the exponents.

Let's just ignore the bases so it'll look less confusing.

3p + 3 = 15

Subtract 3 from both sides.

3p = 12

Divide both sides by 3.
