Oksanka [162]

Discount are used to reduce the costs of items

The percent paid to determine the advertisement is incorrect

<h3>How to determine the correct percentage</h3>

The initial prices are given as: $44.00 to $152.00

And the discount is: 45% to 51%

At a discount of 45%, the price of the items would be:

$Price = \$44.00 * (1 - 45\%)$

$Price = \$24.2$

$Price_2 = \$152.00 * (1 - 45\%)$

$Price_2 = \$83.6$

At a discount of 51%, the price of the items would be:

$Price = \$44.00 * (1 - 51\%)$

$Price = \$21.56$

$Price_2 = \$152.00 * (1 - 51\%)$

Solve the following equation for N 1/5 (N+3)+4=3/10 (2N-2) n = ________

postnew [5]

Answer:

n = 13

Step-by-step explanation:

1/5(n + 3) + 4 = 3/10(2n - 2)

~Simplify both sides

1/5n + 3/5 + 4 = 3/5n - 3/5

~Combine like terms

1/5n + 23/5 = 3/5n - 3/5

~Subtract 23/5 to both sides

1/5n = 3/5n - 26/5

~Multiply 5 to both sides

n = 3n - 26

~Subtract 3n to both sides

-2n = -26

~Divide -2 to both sides

n = 13

Best of Luck!
