Jasper is twice as old as Simon now. Simon was 1/5 as old as Jasper in 12 years ago. How old is Jasper in 12 years's time?
3241004551 [841]

Answer:

44 years old

Step-by-step explanation:

Let the age of Jasper be j years old now.

<u>Now</u><u>:</u>

Jasper➣ j

Simon ➣ j/2

<u>1</u><u>2</u><u> </u><u>years</u><u> </u><u>ago</u><u>:</u>

Jasper➣ j -12

Simon➣ j/2 -12

Given that Simon's age=⅕(Jasper's age),

j/2 -12= ⅕(j -12)

<em>Multiply</em><em> </em><em>by</em><em> </em><em>5</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>,</em>

2.5j -60= j -12

2.5j -j= 60 -12

<em>Simplify</em><em>:</em>

1.5j= 48

<em>÷</em><em>1.5</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

j= 48 ÷1.5

<em>Simplify:</em>

j= 32

<u>12 years time:</u>

Jasper➣ j +12

Thus, Jasper's age

= 32 +12

= 44

70 POINTS!! You buy a video game system for $259 that, is 31% off the original price. What is the original price of the system t
Klio2033 [76]

Answer:

The students mistake was that he took 31% of the new price and added it to the new price. He should have taken 69% of his new price and added it to his new price. The original price was $375.36

Step-by-step explanation:

Lets work it out and compare our work. Since its 31% off, the formula we need to use is original times percent off equals the new price. Let x equal the original.

x*.69=259

Divide both sides by .69

(x*.69)/.69=259/.69

Divide

x=375.36

The original price was $375.36

The students mistake was that he took 31% of the new price and added it to the new price. He should have taken 69% of his new price and added it to his new price.
