Answer:
The cost of the bench is <u>425 dollars</u>.
Step-by-step explanation:
<u>Let x represent the garden table.</u>
<u>Let y represent the bench.</u>
x + y = 804
x = y - 46
<u>Use the substitution method.</u>
y - 46 + y = 804
2y - 46 = 804
<u>Add 46 to both sides.</u>
2y = 850
<u>Divide both sides by 2.</u>
y = 425
