Harley is saving money for a school trip. she has made 15 bracelets and 20 bookmarks to sell. she expects to earn $195. if the bracelets cost 3 times as much as the bookmarks, how much does each bracelet and bookmark cost?

bookmarks cost $3 and bracelets cost $9

explanation:

(Bracelets = b)

(Bookmarks = m)

15b + 20m = 195

Bracelets cost 3 times as much as bookmarks

b = 3m

Substitute b for 3m

15(3m) + 20m = 195

Multiply 15 and 3

45m + 20m = 195

Add 45 and 20

65m = 195

To get m on its own, divide 65 from both sides.

195 divided by 65 is 3

m = 3

Bookmarks cost $3

Bracelets cost 3 times as much as bookmarks

So $3 × 3 = $9

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%
