x = 3
The price after the discount was $45.
When the sporting goods store bought the snowboard and marked it up by 25%, the price became:
<em>= Original cost x ( 1 + markup percentage)</em>
= 120 x ( 1 + 25%)
= 120 x 1.25
= $150
The snowboard was then discounted by 70%, the new price becomes:
<em>= Current price x ( 1 - discount rate)</em>
= 150 x ( 1 - 70%)
= 150 x 30%
= $45
In conclusion, the price after the discount was $45.

Answer:
28.9
Step-by-step explanation:
Using cosine, we get the equation cos(21)=x/31. Solving cos(21), we get about 0.933. Then we multiply by 31 to get about 28.9.
Basically when reading the value of a digit we start from the right.
Digits from the right to the left are named as follows:
units......>no zeros/digits after them
tens......> 1 zero/digit after the digit
hundreds.......> 2 zeros/digits after the digit
thousands......> 3 zeros/digits after the digit
ten thousands.......> 4 zeros/digits after the digit
hundred thousands.........> 5 zeros/digits after the digit
million........> 6 zeros/digits after the digit
Applying this concept to the above mentioned number, we will find that the period containing "913" is called nine hundred and thirteen thousands.
