8 0

Answer:

a) Finding value of y:

8y+4+4y+7=107

12y+11=107

12y =107-11

12y =96

y = 96/12

y = 8

b) RS= 8y+4

= 8(8)+4

= 64+4

= 68

ST= 4y+7

= 4(8)+7

= 32+7

= 39

The value of a jewel in 2015 was $17500. The jewel was purchased in 2008, and its value appreciated 2.5%

ArbitrLikvidat [17]

Answer:

$14722.14

Step-by-step explanation:

We are given that

In 2015

The value of jewel=$17500

Rate of appreciation, r=2.5%

We have to find the initial value of the jewel when it was first bought.

Time, n=7 years

Final value= $Initial\;value (r/100+1)^n$

Using the formula

$17500=Initial\;value(2.5/100+1)^7$

$17500=Initial\;value(1.025)^7$

$Initial\;value=\frac{17500}{(1.025)^7}$

Initial value=$14722.14

Hence, the the initial value of the jewel when it was first bought=$14722.14
