Question

timis mom filled the gas tank in her SUV and spent $72.00 for 22.5 gallons of unleaded gas. What is the constant of proprotionality in this situation

Answer 1

Answer:

The constant of proportionality for this situation is 3.2

Step-by-step explanation:

For the given situation we can say that, the amount spent to fill the gas directly varies with the number of gallons of gas filled.

We can say,

$\ 72.00=k\times 22.5$

where $k$ is the constant of proportionality which is nothing but the units rate of gas in dollars per gallon.

Dividing both sides by 22.5 to find $k$

$\frac{72.00}{22.5}=\frac{k\times 22.5}{22.5}$

∴ $k=3.2$

Unit rate of gas = $3.2/gallon

∴ The constant of proportionality for this situation is 3.2.
