lincoln bought 3 bottles of an energy drink for $4.50. write an equation relating the total cost y to the number of energy drinks bought x. write the equation in the form y = kx.

lincoln bought 3 bottles of an energy drink for $4.50. write an equation relating the total cost y to the number of energy drinks bought x. write the equation in the form y = kx.

Answer

Explanation:

Step1: Find the cost per bottle

We know that 3 bottles cost $4.50. To find the cost per bottle (the value of $k$ in $y = kx$), we divide the total cost by the number of bottles. So $k=\frac{4.50}{3}$. $k = 1.5$

Step2: Write the equation

Substitute $k = 1.5$ into the form $y=kx$. The equation relating the total cost $y$ to the number of energy - drinks bought $x$ is $y = 1.5x$.

Answer:

$y = 1.5x$
