Sue bought ten items at an average price of $3.60. The cost of eight of the items totaled $30. If the other two items were the same price, what was the price she paid for each ?1) $15, 2) $7.50, 3) $6, 4) $3, 5) $1.50I guess the answer is $7.50.What is yr answer ???

Answers

4) $3
Total price of the 10 items= $3.6x10=$36
The cost of the other two items=$36-$30=$6
The cost of each of the two= $6/2(because they are the same price)
                                       =$3


The answer is 4.) $3 each

She bought 8 items at $30 so those cost $3.75 each

8*$3.75=$30 

then add $6 +30= $36

$36/10 = $3.60 for average cost of each item

so the other 2 items cost $3 each

2.5 because rational numbers can be written as fractions, but integers written as fractions have to be able to be written over 1. For example 3 is an integer because 3 = 3/1. But 2.5 isn't an integer because 2.5 = 5/2.

Answers

Given:
gross pay for the week: 320

FICA - Federal Insurance Contribution Act
Social Security Tax = 6.2% of his wages
Medicare Tax = 1.45% of his wages

SST = 6.2% * 320 = 19.84

For, the ordered pair, (x,y)

x= Domain

y=Range

For, the Set G ,Consisting of ordered pair

   = {(-1, 7),(-8, 2),(0, 0),(6, 6)}

⇒Domain of G = {-1, -8, 0,6}

⇒Range of G= {2, 7, 0, 6}
