A $1,000 TR Global bond at 80.5 pays 6% interest. Find the annual yield.

lakkis [162]

Hi there

Annual yield=annual interest÷bond cost

Annual interest=1,000×0.06=60

Bond cost=1,000×0.805=805

So
Annual yield=60÷805=0.0745×100
=7.45%

Good luck!

7x + 8y = 25 9x + 10y =35 elimination method please

$7x +8y = 25 ~~~....(i)\\\\9x +10y = 35~~~ ....(ii)\\\\\text{Multiply equation (ii) by}~ \dfrac 79 ~ \text{and do (ii) - (i):}\\\\\dfrac 79 (9x +10y) - (7x +8y) = \dfrac 79 (35) - 25\\\\\\\implies 7x +\dfrac{70y}9 - 7x -8y = \dfrac{245}9 -25\\\\\\\implies - \dfrac{2y}9 = \dfrac{20}9\\\\\\\implies -2y =20\\\\\implies y =-10\\\\\text{Substitute}~ y = -10~ \text{in equation (i):}\\\\\\7x +8(-10) = 25\\\\\implies 7x = 25 +80\\\\\implies 7x = 105 \\\\\implies x =15\\\\$
