Question

kenneth entered the amount he charged on his credit card each month into a spreadsheet. kenneths credit card charges month amount july $67 august $94 september $54 october $69 november $93 according to the table, when was the rate of change greater? between july and october between september and november

Explanation:

Step1: Calculate rate of change between July and October

The formula for rate of change is $\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1$ (July) = 1, $y_1 = 67$, $x_2$ (October) = 4, $y_2 = 69$.
$\frac{69 - 67}{4 - 1}=\frac{2}{3}\approx0.67$

Step2: Calculate rate of change between September and November

$x_1$ (September) = 3, $y_1 = 54$, $x_2$ (November) = 5, $y_2 = 93$.
$\frac{93 - 54}{5 - 3}=\frac{39}{2} = 19.5$

Answer:

Between September and November
