Which place is the better but
lawyer [7]

Answer:

Stop and Save

Step-by-step explanation:

Find the cost of one apple in each place.

<u>Quick Market</u>:

Divide the total cost with the amount of apples:

1.08/3 = 0.36

The cost for one apple in <em>quick market </em>is $0.36

<u>Stop and Save</u>:

Divide the total cost with the amount of apples:

1.10/5 = 0.22

The cost for one apple in <em>Stop and Save</em> is $0.22

-----------------------------------------------------------------------------------------

$0.22 < $0.36 ∴ <em>Stop and Save</em><em> </em>is cheaper than Quickmarket by $0.14, making Stop and Save your answer.

Which functions have an additive rate of change of 3? Select TWO options
Pachacha [2.7K]

Answer:

Second table.

Step-by-step explanation:

A function has an additive rate of change if there is a constant difference between any two consecutive input and output values.

The additive rate of change is determined using the slope formula,

m =  \frac{y_2-y_1}{x_2-x_1}

From the first table we can observe a constant difference of -6 among the y-values and a constant difference of 2 among the x-values.

m =  \frac{ - 9- - 3}{4-2}  =  - 3

For the second table there is a constant difference of 3 among the y-values and a constant difference of 1 among the x-values.

The additive rate of change of this table is

m =  \frac{ - 1 -  - 4}{3 - 1}  = 3

Therefore the second table has an additive rate of change of 3.
