Shawna is buying a rug for her room store a has the rug for $45 with a 10% discount store B has the same rug for $46 and is offering a $10 off coupon the sales tax is 6% on either purchase if sauna only has $40 to spend which store will see purchased a rug from and how much better Will she have left over

Shawna buys her rug at STORE B and she has $1.84 left over after purchasing her rug.

Step-by-step explanation:

Store a

Store a sells their rug for $45

Store a offers a discount of 10%

Discount = 10% × $45 = $4.5

Amount payable after discount = $45 - $4.5

= $41.5

There is a sales tax of 6%

The total amount payable

Amount of sales tax + Discounted price of rug

Amount of sales tax = 6 % × $41.5

= $2.472

= Discounted amount + Sales tax

= $41.5 + $2.472

=$43.972

Store b

Store a sells their rug for $46

There is a sales tax of 6%

The total amount payable

Store b offers a 10 dollar coupon off for the rug

= $46 - 10

Amount payable after = $36

Amount of sales tax + price of rug(After coupon is deducted)

Amount of sales tax = 6 % × $36

= $2.16

Amount payable by Shawna in Store a = $36 + Sales tax

= $36 + $2.16

=$38.16

Since Shawna has , only $40 to spend, she buys her rug at STORE B

The amount she has left = $40 - $38.16

= $1.84

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

i think the answer is true
