How to find two different ways to find the new value after the original value is increased by 30%
maria [59]

The new value after the original value is increased by 30% is 1.3 times the original value.

<h3>Percentage</h3>

Percentage is used to express a fraction number or decimal in fraction of hundred. It is given by:

Percentage = [(new value - original value) / original value] * 100%

Let x represent the new value and y represent the original value, hence:

30% = [(x - y)/y] * 100%

0.3 = (x - y)/y

x - y = 0.3y

x = 1.3y

The new value after the original value is increased by 30% is 1.3 times the original value.

a manufacturer of bicycle parts requires that a bicycle chain have a width of 0.3 inch with an absolute deviation of at most 0.0
quester [9]

Answer:

|w-0.3| \leq 0.0003

And solving we got:

-0.0003 \leq w-0.3 \leq 0.0003

0.3-0.0003 \leq w \leq 0.3+0.0003

0.2997 \leq w \leq 0.3003

Step-by-step explanation:

For this case we can define the following notation:

W represent the width

And we want a maximum error of 0.0003 so we can set up the following equation:

|w-0.3| \leq 0.0003

And solving we got:

-0.0003 \leq w-0.3 \leq 0.0003

0.3-0.0003 \leq w \leq 0.3+0.0003

0.2997 \leq w \leq 0.3003
