Answer:
$600!
Step-by-step explanation:
First, to find out how much it is per square foot, divide the cost by the amount he paid for (150/60). This comes to 2.5. So $2.50/square foot. However, we need to know how much he will pay for 240 more square feet. So multiply 2.5 by 240 and you get 600. So, for 240 square ft more roofing, Mr. Lou would pay an additional $600. Hope this Helps!

Answer:
There is no unique solution to this problem and there are infinite number of possible solutions which can satisfy these equations.
Step-by-step explanation:
Let S represents Prana's savings account and C represents Prana's chequing account.
Prana has a savings account and a chequing account with a total balance of $85.
Mathematically,
S + C = 85 eq. 1
His parents doubled the amount in each account and the new total balance is $170.
Mathematically,
2(S + C) = 170
2S + 2C = 170 eq. 2
We have two equations and two unknowns.
S + C = 85
S = 85 - C
Substitute the above equation into eq. 2
2S + 2C = 170
2(85 - C) + 2C = 170
170 - 2C + 2C = 170
2C + 2C = 170 - 170
0 = 0
So what does it mean?
it means that there is no unique solution to this problem and there are infinite number of possible solutions which can satisfy these equations.
B=3c/d/ + a simplifying both sides of the equation then isolating the variable
