Hello, hope this will help:)
Answer:
Don't accept A-G
Accept only A-E
Step-by-step explanation:
The company would those projects with a return of return equal to or higher than its cost of capital of 10.45%
Project A with a 12% return is acceptable.
Project B with a 11.5% rate of return is also acceptable
Project C has a rate of return of 11.2% , hence acceptable.
Project D has 11% rate of return and it is therefore acceptable.
Project E has 10.7% return rate and it is acceptable.
Project F has a lower rate of return of 10.3%, hence rejected, as well as projects G

Answer:
Sister = 15 years old
Brother = 12 years old
Step-by-step explanation:
Right now, if the brother is B years old and the sister is S years old, B = (4/5)S because the ratio from brother to sister is 4:5, so if one unit is X, B = 4X and S = 5X
Three years ago, the brother was B-3 years old and the sister was S-3 years old. Keeping one unit as X, we have
B = 3X
S = 4X
B-3 = (3/4)(S-3)
Therefore, we have a system of equations
B = (4/5)S
B-3 = (3/4)(S-3)
Substitute (4/5)S for B into the second equation to only have one variable
(4/5)S - 3 = (3/4)(S-3)
(4/5)S - 3 = (3/4)S - 9/4
add 3 to both sides and subtract (3/4)S from both sides to isolate the variable and its coefficient
(1/20)S = 3/4
multiply both sides by 20 to isolate the S
S = 15
B = (4/5)S = 12
