Question

You are making a recipe that calls for cream of mushroom soup. There is a deal at the store, where you can buy 10 cans of soup for 13$. You only need 6 cans for the recipe.How much will 6 cans cost?

Answer 1

The cost of 6 cans of soup = $7.8

Explanation:

The cost of 10 cans of soup = $13

The number of cans needed for the soup = 6

Now, Cost of 1 can of soup =
`\frac{\textrm{Total cost of 10 cans of soup}}{\textrm{10}}`

= $13 / 10 =$1.3

⇒The cost of 1 can of soup is $1.3

Now, The cost of 6 cans of soup = 6 x Cost of 1 can

⇒ 6 x $1.3 = $7.8

Hence, the cost of 6 cans of soup = $7.8
