Mark bought a new video game priced at $49.99. A sales tax of 8% was added to his purchase. How much tax did Mark pay?

Savatey [412]

The tax that Mark had to pay is calculated by multiplying the base price of the video game and the decimal equivalent of the tax percentage. That is,
tax = ($49.99) x (0.08)
= $3.9992
Thus, Mark had to pay approximately $4 for the tax.

A squares side are increased by five inches. Find the length of the original square if the perimeter of the new square is 100 in

Karo-lina-s [1.5K]

Answer:

The length of side of original square is: 20 inches

Step-by-step explanation:

Let x be the length of side of original square

Then x+5 will be the side of new square

Th formula for perimeter is:

$P = 4*side$

As we know the perimeter of the new square we can use the perimeter to find the value of x

$100 = 4 * (x+5)\\100 = 4x+20\\4x = 100-20\\4x = 80\\\frac{4x}{4} = \frac{80}{4}\\x = 20$

The value of x is 20 inches.

Hence,

The length of side of original square is: 20 inches
