Answer:2x -3y=9 .
Step-by-step explanation:
Answer:
$61.18
Step-by-step explanation:
The price last week was an unknown. We will call it x. x is an entire amount, so it is 100% of x.
This week, the price is 15% lower. Since 100% - 15% = 85%, the price this week is 85% of what it was last week. Last week it was x, so this week, the price is 85% of x.
85% of x = $52
0.85x = $52
Divide both sides by 0.85:
0.85x/0.85 = $52/0.85
x = $61.1764...
