If 5 deli sandwiches cost 29.75, how much will 8 sandwiches cost?

$47.60

Step-by-step explanation:

Equation for direct variation between two variables x and y .

            (1)

We assume that the cost of sandwiches is directly proportional to the number of sandwiches .

Given : 5 deli sandwiches cost $29.75.

To find : Cost of 8 sandwiches.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

use formula for the circle a=3.14
