Question

Jordan and his friends bought a few items from a store. a bag of chips is 1/4 the cost of a sandwich . A soda is 3$less than a sandwich.

Write an expression to represent the items

Answer 1

I have the same answer and I don't knownit

Answer 2

I’m not sure if the expression should be for the cost, which can be shown by:
(9/4)x - 3 = total cost of the items, where x is the cost of a sandwich.

For the items individually,
(1/4)x = y, where y is the cost of a bag of chips.
x - 3 = z, where z is the cost of a soda.
Combining each individual expression, it becomes:
x + y + z = total cost.
(x) + ((1/4)x) + (x-3) = total cost
= (9/4)x - 3

This assumes Jordan and his friends bought a sandwich + soda + bag of chips.




You could try writing without variables to help picture the expression:
(1/4)sandwich = bag of chips
and
sandwich - $3 = soda

If x represents the cost of a sandwich, this can be rewritten as:
x + x - 3 + (1/4)x

There are like terms with x, so it can simplify further: (9/4)x - 3 = total cost of the items.
Hopefully this makes sense!
