Nya wants to buy a sweater that had an original price of $55. The sweater is now discounted 20% and the sales tax rate is 5.5%.
suter [353]

Answer:

$46.42

Step-by-step explanation:

a=price after discount (without sales tax)

a/55=20/100

100a=55·20

100a/100=1,100/100  (the 1,100 is from the 55·20)

You get 11 and then you have to subtract 11 from 55.

55-11=44, so a=44

Then you multiply 44·0.055         (you get 0.055 because you have to make 5.5% a decimal.  You get 2.42.

You add 2.42 and 44 and you get $46.42

A company has 6582 to give out in bonuses. An amount is to be given out equally to each of 32 employees A manger Jake has reason
just olya [345]

Answer:

His estimate is not correct

Each employee gets 205.6875

Step-by-step explanation:

Bonus to give out = 6582

Number of employees to get bonus = 32

Bonus per employee = Total bonus / number of employees

= 6582 / 32

= 205.6875

Each employee will get 205.6875 contrary to manger Jake reasoning of 2000 per employee

manger Jake reasoning

6572 / 32

32 in 65 = 2 remainder 1

He added 000 zeros to 2 which is wrong

He should have added 00 zeros to 2 because he has 172 remaining after dividing 65 by 32

Which ordered pairs cause this relation NOT to be a function? Why?
dangina [55]

Answer:

(3,1) and (3,2)

Step-by-step explanation:

We are given that a relation

{(0,0.5),(0.5,1),(3,1),(1,6),(3,2)}

We have to find that ordered pair which causes this relation not to be a function.

We know that

Function: It is  a mapping between two non- empty set A and B.

Every element of set A has unique image in set B.

One element of set A can not have two or more images in set B.

Two or more elements of set A have same images in set B.

In given relation images of 3 are 1 and 2 which is not possible if a relation is function because one element can not have two or more images.

The ordered pair (3,2) and (3,1) cause this relation not to be a function because image of 3 are 1 and 2 which is not possible .

Answer: (3,1) and (3,2)
