Answer:
bench costs 450
Explanation:
let the bench cost be b and cost of table be t, then
t = b - 97 ( 97 less than bench )
then sum the 2 items and equate to total cost , that is
t + b = 803 ( substitute t = b - 97 into the equation )
b - 97 + b = 803
2b - 97 = 803 ( add 97 to both sides )
2b - 97 + 97 = 803 + 97 ( simplify )
2b = 900 ( divide both sides by 2 )
b =
, that is b = 450
the cost of the bench is 450
