To find the price of 3 cans, we can use the concept of proportionality. Given:

• Price of 8 cans = $2.50

We can set up a proportion to find the price of 3 cans:

$\frac{8 \text{ cans}}{2.5} = \frac{3 \text{ cans}}{x}$

Where $x$ is the price of 3 cans.

Cross-multiply to solve for $x$:

$8x = 2.5 \times 3$

$8x = 7.5$

$x = \frac{7.5}{8} = 0.9375$

So, the price of 3 cans is $0.9375.
