balandron [24]

Answer:

715 pounds

Step-by-step explanation:

<em>FV = solve</em>

<em>PV = 600</em>

<em>I% = 6</em>

<em>K = 1, N = 3 </em>(2013 - 2016 = 3 years)

Plug it in:

<em>FV = 600 x [ 1 + (6/100 x 1)]³</em>

= 600 x ( 1 + 0.06)³

= 600 x (1.06)³

FV = 714.61, 715 to the nearest dollar.

<em>Therefore, the fee in 2016 is 715 pounds.</em>

The length of a rectangle is five centimeters more than twice its width. The perimeter is 100 centimeters. Use Guess and Check t
Nikolay [14]

Guessing and checking isn't the best solution, so I will demonstrate it another way.

Let x be the width. We know that the length is then 2x+5.

So, 2(x+2x+5)=100

3x+5=50

3x=45

So, x=15.

Therefore, the rectangle is 15 centimeters wide.

Guessing and checking could also work. Once you plug in a value, if it is less than 100, than increase you number. The other way works as well.
