Let d = # digital cameras
Let m = # manual cameras
d + m = 240 equation 1
(d-82) = 3(m-26) equation 2
d - 82 = 3m - 78
d - 3m = 82 - 78
d - 3m = 16 equation 2 simplified
We have two equations with 2 unknowns:
d + m = 240
d - 3m = 16 subtract equation 1 from equation 2
---------------
-4m = -224
m = -224/-4
m = 56
d + m = 240
d = 240-m
d = 240-56
d = 184
He started with 184 digital cameras and 56 manual cameras

Answer:
B; 125
Step-by-step explanation:
45% of 500 is 225. 20% of 500 is 100
225 - 100 = 125
Hope this helps :)
The total lateral surface area
This is the area of the sides of the figure. In this case it will be the sum of the three rectangles.
(13) * (14) + (13) * (14) + (14) * (10) = 504yd ^ 2
the total surface area.
This is the surface area of the whole figure. In this case there are three rectangles and two triangles.
(13) * (14) + (13) * (14) + (14) * (10) + (1/2) * (10) * (12) + (1/2) * (10) * (12 ) = 624 yd ^ 2
the answer is
total lateral surface area: 504yd ^ 2
total surface area: 624 yd ^ 2
