Answer:
Mean costing = $3,768
Step-by-step explanation:
Given:
Mean A(x) = 260
Rate = $10 per feet
Fixed charge = $1,168
Computation:
Assume;
depth = x ft
So,
Cost of company B = 10x + 1,168
So,
Mean costing = 10A(x) + 1,168
Mean costing = 10(260) + 1,168
Mean costing = 2,600 + 1,168
Mean costing = $3,768
Answer:

Step-by-step explanation:
It should have been, write problem

Use distributive property.
-4x + 12 = 20
subtract 12 from each side
-4x =8
divide each side by -4
x = -2
