We have been given that Grant spent $2.50, $4.00, $4.25, and $3.25 on breakfast in one week. The next week he spent $6 more in total for the 4 breakfasts than the week before. We are asked to find increase in the mean of second week.
Since Grant spent $6 more than last week, we will divide 6 by 4 to get how much mean of second week breakfast expenditures increased with respect to first week expenditures.
Therefore, mean of second week breakfast expenditure will be $1.5 more than first week.

Answer:
<h2><em>
<u>Domain = (-∞, ∞) Range = (-∞, ∞) </u></em></h2><h2>
Step-by-step explanation:</h2><h2>The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.</h2><h2>Interval Notation:</h2><h2>(−∞,∞)</h2><h2>Set-Builder Notation:</h2><h2>{x|x∈R}</h2><h2>The range is the set of all valid y</h2><h2>values. Use the graph to find the range.</h2><h2>Interval Notation:</h2><h2>(−∞,∞)</h2><h2>Set-Builder Notation:</h2><h2>{y|y∈R}</h2><h2>Determine the domain and range.</h2><h2>Domain: (−∞,∞),{x|x∈R}</h2><h2>Range: (−∞,∞),{y|y∈R}</h2><h2>image of graph</h2><h2 />
