Toko sepatu memberi diskon 30% untuk semua barang. Jika tasya membeli sepasang sepatu dan ia membayar Rp 336.000,00 setelah mendapat diskon, harga sepasang sepatu tersebut sebelum diskon adalah

IDR 480,000

Step-by-step explanation:

Persentase diskon = Harga lama - Harga baru / Harga lama

Harga lama = Harga sebelum diskon = x

Harga Baru = IDR 336000

Persentase diskon = 30%

Karenanya:

30% = x - 336000 / x

30/100 = x - 336000 / x

0.3 = x - 336000 / x

Cross Multiply

0.3 × x = x - 336000

0.3x = x - 336000

x - 0.3x = 336000

0.7x = 336000

x = 336000 / 0.7

x = IDR 480,000

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
