Jewel is 7 years old and John is 16 years younger than Dave. One year ago, Dvae's age was twice the sum of Jewel's and John's ag
ivanzaharov [21]

Answer:

Jewel is 7 years old

John is 1 year old

Dave is 17 years old

Step-by-step explanation:

From the question we are told that:

Jewel age is J=7 years

John age J'=(D-16)years

Dave's age a Year ago

 D-1=2(J-1+J'-1)

So that Dave.s age this Year could be

 D=2((J-1)+(J'-1))+1

Simplifying Equation for Dave's age we have

 D=2((7)-1+(D-16)-1)+1

 D=2(6+D-15)+1

 D=2(D-9)+1

 D=2D-18+1

 D=17 Years

Dave is 17 years old

Therefore

Johns age is

 J'=(D-16)

 J'=17-16

 J'=1year old

John is 1 year old

<h3>Answer: Choice C) $1,444.50</h3>

========================================================

There are two methods to get the answer.

The slightly longer method is to take 7% of the original price to get

7% of 1350 = (7/100)*1350 = 0.07*1350 = 94.50

The sales tax is $94.50

Add this onto the original price to get 1,350+94.50 = 1,444.50

----------------------------

A shortcut is to multiply the original price by 1.07

The multiplier 1.07 represents a 7% increase since

  • 1 = 100%
  • 0.07 = 7%
  • 1.07 = 1 + 0.7 = 100% + 7%

So we will have 1.07*1350 = 1,444.50
