The correct answer is:
2u-v=7(5i-3j)
Therefore, 5, and 3 go inside the box.

x times (x+1).
If it's wrong, then I'm an idiot.
Step-by-step explanation:
Let x be marked up price. We have been given that a chemistry set costing $27.50, marked up 32% on cost.



Therefore, mark up price is $8.80.
Since we know that selling price of any item equals the sum of cost and mark-up price of the item.
Let us find selling price of our chemistry set.

Therefore, the selling price of the chemistry set is $ 36.30.
