Answer 1

Answer:

The cost to fill the new family size box will be $\ 2.93$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> the scale factor

we have

$z=1.25$

so

$z^{3}=1.25^{3}=1.953125$

To find the new cost multiply the original cost by the scale factor elevated to the cube

$\ 1.50(1.953125)=\ 2.93$

The new volume would be

$17(1.953125)=33.20\ ounces$
