A store sells 4 cans of beans for $9. What is the price of 7 cans of beans?

Answer 1

If 4 cans of beans cost $9, then we can use proportionality to find the cost of 7 cans of beans:

4 cans / $9 = 7 cans / x

where x is the unknown price of 7 cans.

To solve for x, we can cross-multiply to get:

4 cans * x = 7 cans * $9

Simplifying the right-hand side gives:

4 cans * x = 63 dollars

Dividing both sides by 4 cans gives:

x = 63 dollars / 4 cans

So the price of 7 cans of beans is:

7 cans * $ (63 dollars / 4 cans) = $15.75

Therefore, 7 cans of beans cost $15.75.
