What would be the total cost of purchasing the number of shirts needed to use your coupon-after
your coupon is applied and a 7,5% sales tax is charged on the purchase? Show work.

$35.66

Step-by-step explanation:

$17.99 shirt x 20% discount = $3.60

$17.99 reg price tshirt - $3.60 discount = $14.39 per shirt

$14.39 per shirt x 3 shirts = $43.17 before taxes

$43.17 sale price for 3 shirts - $10 coupon = $33.17 base price

$33.17 x 7.5% sales tax = $2.49

$33.17 + $2.49 = $35.66 total

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
