A prism has total surface area of 228 m^2 and volume of 216 m^3.

1 answer:

5 0

Original and bigger prism are similar with scale factor k = 4, so:

new surface area = k² * original surface area = 4² * 228 = 16 * 228 = 3648 m²
and
new volume = k³ * original volume = 4³ * 216 = 64 * 216 = 13824 m³

x ----> the number of drinks that Sarah bought.

y ----> the number of candies that Sarah bought.

we know that

$y=3x$ -----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (2,6)

see the attached figure

therefore

The number of drinks that Sarah bought was 2 and the number of candies that Sarah bought was 6
