Donald's Earnings, x (dollars) Fallons Earnings, y 38 45 43 50 48 55 53 60 58 65 Which equation best represents Fallon's earning
kherson [118]

Given:

The table of values for Fallon's earnings in terms of Donald's earnings.

To find:

The equation that best represents Fallon's earnings in terms of Donald's earnings.

Solution:

In the given table the x-values are increasing by 5 units and  y values increasing by 5 units. It means the rate of change of y with respect to x is constant and the table represents a linear function.

If the graph of a linear function passes through two points, then the equation of linear function is

y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)

Consider any two points from the table. Let the two points are (38,45) and (43, 50). Then, the equation is

y-45=\dfrac{50-45}{43-38}(x-38)

y-45=\dfrac{5}{5}(x-38)

y-45=1(x-38)

y-45=x-38

Adding 45 on both sides, we get

y=x-38+45

y=x+7

Therefore, the correct option is A.

lions [1.4K]

In the question it is given that,

The students at Midtown Middle school sold flowers as a fundraiser in September and October. In October, they charged $1.50 for each flower

And the October price was a 20% increase of the September price.

Let the price of the flower in October be $x

So we have

x+  \frac{20}{100}x = 1.50 \\ \frac{120x}{100} = 1.50 \\ x = \frac{1.50*100}{120} = 1.25

So the price of the flower in Septembet is $1.25 .
