Answer:
The volume ratio of Prism A to Prism B is
Step-by-step explanation:
Step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared
Let
z-----> scale factor
x/y----> ratio of the surface area of Prism A to Prism B
so
we have
substitute
step 3
Find the volume ratio of Prism A to Prism B.
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-----> scale factor
x/y----> volume ratio of Prism A to Prism B
so
we have
substitute
Y= # of pencils
z= # of pens
1y + 1.50z = 7
Total # of pencils and pens combined equals 6
4 pencils = $4
2 pens = $3
$4 + $3 = $7
4 pencils + 2 pens = 6 items total
The answer would be $152.20 because 132*1.153=152.196, rounded to $152.20.
