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.

Put in equation (1)

Hence, the cost of 8 sandwiches = $47.60

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
