Question

If 5 ice creams cones cost 20 dollars,
how much would 10 ice creams cost?

Answer 1

The cost of 10 ice-cream cones is 40 dollars.

Step-by-step Step-by-step explanation:

Here we have given that the cost of 5 ice-creams cone is 20 dollars. So, finding the cost of 1 ice-cream cone.

`:\implies{\tt{Cost \: of \: 1 = 20 / 5}}`

`:\implies{\tt{Cost \: of \: 1 = (20)/(5)}}`

`:\implies{\tt{Cost \: of \: 1 = \cancel{(20)/(5)}}}`

`:\implies{\tt{Cost \: of \: 1 = \$4}}`

Hence, the cost of 1 ice-cream cone is 4 dollars.

Now, we know the cost of 1 ice-cream cone. Thus, finding the cost of 10 ice-cream cones.

`:\implies{\tt{Cost \: of \: 1 = \$4}}`

`:\implies{\tt{Cost \: of \: 10 = 4 * 10}}`

`:\implies{\tt{Cost \: of \: 10 = \$40}}`

Hence, the cost of 10 ice-cream cones is 40 dollars.
