Answer:
The selling price would be $420.
Step-by-step explanation:
In order to find the mark up, we need to multiply the amount it originally costs by the percentage it is being marked up.
$300 * 40% = $120
Now that we have the mark up amount, we add it to the original cost to get the sale price.
$300 + $120 = $420
1. <u><em>a=-1+b/7 is the right answer.</em></u> First you had to add by b from both sides of equation, and it gave us, 
. And then simplify, and it gave us, 
. Divide by 7 from both sides of equation, and it gave us, 
. Finally simplify, and it gave us the answer is a=-1+b/7 is the right answer.

2. <em><u>a=-b-1/2 is the right answer.</u></em> First you had to add by 2b from both sides of equation, and it gave us, 
. And then simplify, and it gave us, 
. Next you can also divide by -4 from both sides of equation, and it gave us, 
. Finally simplify, and it gave us the answer is a=-b-1/2 is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
