What is the constant proportionality

The relationship between price and the number of empanadas is PROPORTIONAL.

1 Empanada = 50 cent = $0.5

Constant of PROPORTIONALITY = ½

Step-by-step explanation:

From the given table:

2 Empanadas = $1

6 Empanadas = $3

We see that, as the number of Empanadas increases, the amount in Dollars also increases. Such that:

Let E = Empanadas

$ = dollar

~ = sign of PROPORTIONALITY.

Therefore:

$ ~ E

$ = KE

Where K = constant of proportionality.

When E = 4; $ = 2

$2 = K4

K= 2/4

K = ½

$ = ½E (Binding formula)

This applies for all the number of Empanadas bought.

Let's start with the known information.
There is a set value, which is $25.50. Next it was given that the rate is $1.50 per mile. Lastly, Jack does not want to spend more than $60 total.
With these information, you can set up an inequality.
Let x be the number of miles.
1.50x + 25.50 ≤ 60
Subtract 25.50 on both sides
1.50x ≤ 34.50
Divide both sides by 1.5
x ≤ 23
This means that the greatest number of miles Jack can drive is 23.
