Answer:
<u><em>Answer is below</em></u>
Step-by-step explanation:
<u><em>10=3x-8</em></u>
<u><em>always remember to flip the equation</em></u>
<u><em>3x-8=10</em></u>
<u><em>Add 8 to both sides</em></u>
<u><em>3x-8(+8)=10(+8)</em></u>
<u><em>3x=18</em></u>
<u><em>Divide both sides by 3</em></u>
<u><em>3x/3=18/3</em></u>
<u><em>x=6</em></u>
7 times 6 is 42
91 divided by 7 is 13
15. 5 times 3 is 15.
If you check, 15 divided by 3 is 5(red cars).
Simple, finding markdown, use these two formulas.
Markdown=Original-New
and
Percent Markdown= Markdown Amount/Original*100
So,
Markdown=612-450
M=162
Markdown%= 162/612*100
M%=0.2647*100
M%=26.5 (rounded)
Thus, there was a 26.5% decrease.
Answer:
$5.40
Step-by-step explanation:
To find the increase we need to consider our variables.
Current Rate = $4.50
Increase Percentage = 20% or 0.20
Now we can find the new rate by multiplying the Current Rate to the Increase Percentage and add it to the Current Rate again.
Total Price w/ Increase = ($4.50 x 0.20) + $4.50
Total Price w/ Increase = $0.90 + $4.50
Total Price w/ Increase = $5.40
