The original price of a skateboard was $85. The owner of the store
lora16 [44]

Answer:

\$68

Step-by-step explanation:

1. Approach

To solve this problem, one wants to find the price of a product after its discount has been applied. The discount is 20% off, so the new price of the item is 80% of its original price (percent is out of 100 so if a an item is 20% off, it is 100 - 20 = 80; 80% the original price). To calculate the percent cost, one would divide the percent value by 100, and then multiply it by the price of the item.

2. Solving

The price of the new item is 80% of the price of the original item.  To calculate the percent cost, cent, one would divide the percent value by 100, and then multiply it by the price of the item.

Therefore, the equation that will be formed is,

price * \frac{percent}{100}

Substitute,

85 * \frac{80}{100}

Simplify,

85 * 0.8\\\\= 68

Graph an inequality on a number line: 15>m
barxatty [35]

When the sign is ≤ or ≥ ("less/greater than <u>or equal to</u>"), the dot if filled in.

When the sign is < or >, the dot is not filled in/open circle.


15 > m

[15 is greater than m, or m is less than 15]

Since m is less than 15, the arrow is going to the left (the numbers to the left are less than 15)
