Answer:
Step-by-step explanation:
Here's a completely valid trick for finding the equation of this new line:
Start with the given 2x + 4y = 6. Replace that '6' with 'C.' We need to find C. To do this, replace x with 6 and y with 4 and calculate C:
2(6) + 4(4) = C, or 12 + 16 = C. Thus, C = 28, and the desired equation is
2x + 4y = 28, or (in simplified form) x + 2y = 14
Answer:
$568.75
Step-by-step explanation:
To find the markup, we multiply the original price by the percentage of markup
Markup = 175 * 225%
=175 * 2.25
=393.75
The new price is the markup plus the original price
New price = markup+ original price
=393.7+175
=568.75
