A store sells 8 cans of nuts for $20. How much would it cost you to buy 7 cans of nuts?

To find the cost of 7 cans of nuts, we first need to determine the price per can.

Given:
- 8 cans cost $20.

The price per can is:

\[
\text{Price per can} = \frac{20}{8} = 2.50 \text{ dollars per can}.
\]

Now, to find the cost of 7 cans:

\[
\text{Cost of 7 cans} = 2.50 \times 7 = 17.50 \text{ dollars}.
\]

So, the cost to buy 7 cans of nuts is **$17.50**.
