Shang has a coupon for 15% off he decided to buy a shirt for 16.95 the sales tax rate is 6% what is his final cost
kati45 [8]

Answer:

After the coupon and sales tax were applied, he paid $15.27 for the shirt.

Step-by-step explanation:

We are given that a shirt is $16.95. This is reduced by 15% due to the coupon.

100\% - 15\% = 85\%

Therefore, 85% of the shirt price is still active.

\displaystyle \frac{85}{100}=0.85

We can multiply this value by the shirt price to find the current price.

16.95 \times 0.85 = 14.4075 \approx \$14.41

However, the shirt also has a sales tax of 6% applied after the coupon.

\displaystyle \frac{6}{100} = 0.06a

Now, we need to find the total price for the shirt.

\displaystyle 14.41 \times 1.06 = 15.2746 \approx \$15.27

Therefore, he paid $15.27 for the shirt.

Someone please pass the answers to this
arsen [322]

Answer/Step-by-step explanation:

1. The figure is composed of a triangle and a rectangle.

Area of the triangle = ½*base*height

base = 4 ft

height = 12 - 8 = 4ft

Area of triangle = ½*4*4 = 8 ft²

Area of rectangle = length * width

Length = 8 ft

Width = 4 ft

Area of rectangle = 8*4 = 32 ft²

✔️Area of the figure = 8 + 32 = 40 ft²

2. The figure is composed of a semicircle and a triangle

Area of the semicircle = ½(πr²)

radius (r) = 3 cm

π = 3

Area = ½(3*3²) = 13.5 cm²

Area of triangle = ½*base*height

base = 3*2 = 6 cm

height = 6 cm

Area = ½*6*6 = 6 cm²

✔️Area of the figure = 13.5 + 6 = 19.5 cm²
