Step-by-step explanation:
We are given the following in the question:
Cost of one cupcake = $3.50
Cost of one fruit tart = $3
Total money Harry have = $50
Harry bought 8 cupcakes and
fruit tarts.
We have to write the inequality giving relation between the total number of cupcakes and fruit tarts Harry can buy the amount of money he has.
Total cost of purchase =
= Total cost of cupcakes + Total cost of fruit tarts

Now, this total cost of Harry's purchase should be less than than equal to $50.

is the required linear inequality.
Answer:
We need to add the expression: 
Step-by-step explanation:
As the first step, add the first two polynomials listed in order to find what their sum is. Do such by combining like terms:

now, you need to find another polynomial (let's call it P(x)) such that added to the one we just found above, will render
as a result.
Putting this phrase in mathematical terms, we write:

Now we solve for this unknown P(x) in this equation, by subtracting each of the terms that are accompanying it on the left side of the equation. We do one at a time for clarity:

Therefore, the expression we need to add is:
