A consumer pays $5 more per camera.
Step-by-step explanation:
Let the cost of manufacture of disposable camera in dollars be 
Government taxes imposed on camera = $1.00 per camera
Cost of camera after taxes in dollars 
Wholesale prices raised by manufacturer = $2.00 per camera
Wholesale price of camera in dollars per camera 
Retail prices raised raised by retailer = $2.00 per camera
Retail price of camera in dollars per camera

Thus, a consumer pays $5 more per camera.
Answer:
Distance of the jogger from his house is 7 miles.
Step-by-step explanation:
We are given that,
Distance ran towards east = 3 miles
Distance ran towards east of north = 5 miles
Angle made towards east of north = 30° as shown in the figure below.
<em>So, the total angle by which the jogger ran = 90° + 30° = 120°</em>
Thus, using the cosine law, we get,

i.e. 
i.e. 
i.e. 
i.e. x = ±7 miles
Since, the distance cannot be negative.
Thus, the distance of the jogger from his house is 7 miles.
