If sandwiches were on sale and it cost 28 dollars for 4 sandwiches, how much would it cost for 7 sandwiches?

$49

Step-by-step explanation:

First, we need to figure out how much one sandwich costs.

28 / 4 = 7

One sandwich costs $7

Now we just need to add up 7 sandwiches at $7 each.

7 x 7 = 49

7 sandwiches cost $49

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

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
