Mrs Chen will make a profit which is 12% of the original price, if she sells the necklace at $4144. What will be her profit if she sells the necklace at $4250?

To solve this problem, we first need to find the original price of the necklace.

1. We know that the selling price of $4144 is 112% of the original price because the original price plus 12% profit equals the selling price.

2. To find the original price, we divide the selling price by 112% (or 1.12 in decimal form).

   So, $4144 ÷ 1.12 =$3700. This is the original price of the necklace.

3. Now, we want to find out the profit if the necklace is sold for $4250.

4. The profit is the selling price minus the original price.

   So, $4250 -$3700 = $550.

Therefore, if Mrs Chen sells the necklace at $4250, her profit will be$550.
