Answer: 3(x minus 5.50) = 111.75; the monthly Internet service is $42.75
Step-by-step explanation:
Given the following :
Total amount spent on internet for 3 months = $111.75
Monthly credit received on bill = $5.50
Monthly Credit of $5.50 means $5.50 is deducted from the amount being paid on thir bill monthly.
Assume their monthly internet service fee = x
The amount paid before the credit deduction each month:
Amount paid - credit
(x - $5.50)
For 3 months :
3 × (x - $5.50) = $117.75
3(x - $5.50) = $117.75
Monthly fee paid before credit deduction:
3(x - $5.50) = $117.75
3x - $16.50 = $117.75
3x = $117.75 + $16.50
3x = $128.25
x = $128.25 / 3
x = $42.75
There's no way to tell if we can't see the inequality.
This would be a 4/5 ratio
Order of Operations:
PEMDAS
P: Parenthesis
E: Exponents
MD: Multiplication/Division
AS: Addition/Subtraction
Remember to do them in order.
E.G: 8(2+3)²-4/2
You do first the parenthesis(2+3), which is 6
Multiply 6 by 6(rule of exponents), which is 36.
Multiply 36 by 8, which is 288.
Divide 288 by 2, which is 144.
Subtract 144-2. It is 142.
Answer: 142
