Suppose the price of a certain item increases by 3.8% a total of 5 times, and then decreases by 1.4%
a total of 2 times. by what overall percent did the price increase?

The price was increased by 17.15%

Step-by-step explanation:

step 1

we have that

Let

x -----> the price of a certain item

we know that

If a price increases by 3.8% a total of 5 times

then

The new price will be equal to multiply the original price by 5 times 1.038

so

step 2

we have that

we know that

If a price decreases by 1.4% a total of 2 times

then

The new price will be equal to multiply the actual price by 2 times 0.986

The actual price is

so

convert to percentage

therefore

The price was increased by 17.15%

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
