Answer:
Step-by-step explanation:
We know we have to write an algebraic equation for the sentence - so "translate" the phrases of the sentence step-by-step. Let the unknown number be represented by the variable n, as the question states.
Start with the phrase "the sum of a number and 4.4." A sum comes as a result of adding numbers together - therefore the first part of the equation must be 
.
Next, the sentence says "is 8.1." The "is" indicates that the expression we just wrote equals something, so that number must be 8.1. Therefore, the whole equation must be .
You want 3 loaves of bread, at $1.50 a piece and a jar of jelly, at $4. So set up the equation 3(1.5)+1(4). You don't want peanut butter so that's unnecessary information. Your total is $8.50, so subtract that from 10, you get 1.5. You will have $1.50 left over.
The choice that best supports the claim made by the given sentence is A (No Change).
<h3>What is mathematical reasoning?</h3>
Mathematical reasoning is a part of mathematics where the true or false values of the given statements is determined.
Now, in the given scenario, option A is the correct answer because:
- By mentioning the “specialized” methods used in repair shops, the option A suggests that repairing goods is seen as a specialty rather than as a common activity. This further connects logically with the “rare” repair shops introduced just before the underlined portion.
- B, C, and D are incorrect because none provides information that supports the claim made in the sentence.
Hence, by mathematical reasoning, we can say that the correct choice for the claim of given statement is A i.e., no change.
