<h3>Unit price is $ 0.56 per pound of potatoes</h3><h3>Unit price is $ 3.1 per pound of broccoli</h3>
<em><u>Solution:</u></em>
Given that,
Unit price is the price of 1 unit

<h3><u>Find unit price of potatoes</u></h3>
A shopper paid $2.52 for 4.5 pounds of potatoes

Thus unit price is $ 0.56 per pound of potatoes
<h3><u>Find unit price of broccoli</u></h3>
$7.75 for 2.5 pounds of broccoli

Thus unit price is $ 3.1 per pound of broccoli
Answer:
Option 2: 
Step-by-step explanation:
Given:
From the triangle shown below;
A triangle QRS with angle QRS = 90°, ∠QSR = 30°.
Side QR = 5, SQ = 10 and RS = 5√3
Now, we know from trigonometric ratio that,

Here, opposite side of angle QSR is QR and Hypotenuse is the side opposite angle QRS which is SQ. Therefore,

Therefore, the value of sine of 30° is one-half. So, second option is correct.
<h2>
The bench costs $325</h2>
Cost of bench = x
Cost of garden table = x - 50
x - 50 + x = 700
2x - 50 = 700
2x = 750
x = 325
