A bicycle has a listed price of $544.98 before tax. If the sales tax rate is 9.75%, find the total cost of the bicycle with sale

CaHeK987 [17]

Answer:

$598.12.

Step-by-step explanation:

First you need to make the percent into a decimal and multiply it by the price without tax: 0.0975 · 544.98, which equals 53.136 when rounded to the nearest thousandth. This means that 53.136 is 9.75% of 544.98. Then you just need to add 53.136, or 53.14 when rounded, to 544.98. This gives you $598.12.

Margot is sewing a ribbon on a seam along the perimeter of a square pillow. The side length of the pillow is 2x2 1 inches. She p

Sauron [17]

The expression used for the length of ribbon that she needs for both pillows will be $4(2x^{2} +4x-6)$ .

The total length of the pillow she needs will be 130 inches.

Given,

The side length of pillow is $(2x^2 + 1) \ inches$ .

The side length of another pillow is $4x-7 \ inches$ .

We know that perimeter of square will be,

$P=4\times length$

So the perimeter of pillow will be,

$P=4\times (2x^2+1)\\$

$P=8x^{2} +4$

Similarly, the perimeter of another pillow will be,

$P=4\times (4x-7)$ ]

$P=16x-28$

Hence,the total length of ribbon that she needs for both the pillows will be,

$8x^{2} +4+16x-28\\8x^{2} +16x-24\\4(2x^{2} +4x-6)$

If $x=3.5\\$ then the total length of ribbon will be,

$4(2\times 3.5^{2}+4\times 3.5-6)\\4(2\times 12.25+14-6)\\$

$4(24.5+8)$

$4\times 32.5\\$

$130 \ inches$ .

Thus the required expression will be $4(2x^{2} +4x-6)$ and the total length of ribbon she needs will be 130 inches.

So, the correct option will be (D).
