Answer:
R = 5500t
Step-by-step explanation:
The estimated monthly revenue is said to be 5500 per month. Then for t months, the revenue R will be ...
R = 5500t
_____
<em>Additional comment</em>
We expect costs to be C = 3200t, so profit is ...
P = R -C
P = 5500t -3200t
P = 2300t
At that rate, it will be 50 months before enough profit is earned to pay for the initial cost of the store.
50% is equal to the so we can easily divide 9 by 2 to get your answer 4.50 there is no hundreths for it is a clean divide (4.5×2=9)

2x+2x+4x+150+4x+150=360
12x+300=360
12x=360-300
12x=60

hope this helped !!
Answer:
x≤-91
Step-by-step explanation:
The system of equations representing the number of Blue-ray discs and DVD's after t months are:
507 + 26t
925 - 12t
Each month, the number of DVD's sold decreases by 12, this can be modelled as:
number of DVD in opening month - (monthly decrease x number of months)
Number of DVD's in t months = 925 - 12t
Each month, the number of Blue-ray discs sold increases by 26, this can be modelled as:
number of blue-ray discs in opening month + (monthly increase x number of months)
Number of Blue-ray discs in t months = 507 + 26t
