If x is the amount that Tanya paid for each item, then Tony's items would be x-2.25. So:
3x=4(x-2.25)
3x=4x-9
x=9
x-2.25=6.75
Tanya spent $9 on each item; Tony spent $6.75 on each of his items. ☺☺☺☺
Part A:
Given that <span>Starlight tree farms sells Douglas Firs and Noble First.
Let </span>n be the number of Noble Fir trees sold, then<span> if they sold 139 more Douglas First than Noble Firs, this means that the number of Douglas First trees sold is n + 139.
Given that the total number of trees sold was 377, then we have, n + n + 139 = 377, which means that 2n + 139 = 377
Therefore, the equation that could be used to solve for n, the number of Noble Fir trees sold is 2n + 139 = 377.
Part B:
</span><span>Given that you are driving 55 miles per hour and you must drive a total of 440 miles. If you already driven 275 miles, then, the equation representing the number of hours, h, it will take to reach your destination is given by 55h + 275 = 440.
Subtracting 275 from both sides of the equation gives:
</span>

<span>
Dividing both sides by 55 gives:
</span>

<span>
Therefore, the time it will take you to reach your destination is 3 hours.</span>

Answer:
The markup percent on the painting is 58.3%
Step-by-step explanation:
Here, The Cost price of the painting = $120
The selling price of the painting = $190

or Profit = $190 - $120 = $70
Now, Markup % = (Gross Profit / cost) x 100
⇒Markup % = 
Hence, the markup percent on the painting is 58.3%
