Answer:
$968
Step-by-step explanation:
x= the money John originally had in his savings account
The statement says that John spent $88 on a radio and 1/4 of what was left on presents for his friends. This means that the remaining money is 3/4 of the total amount minus the money spent on the radio:
3/4(x-88)
Then, it says that of the money remaining, John put 4/11 into a checking account and the last remaining $420 was left to charity. Since, he spent 4/11 of the remining 3/4(x-88), the remaining is 7/11 of that and that remaining is equal to $420 that was the money left at the end:
7/11(3/4(x-88))= 420
21/44(x-88)=420
21/44x-42=420
21/44x=462
x=968
According to this, the money that John originally had in his savings account was $968.
He spent $88 on a radio: 968-88= 880
1/4 of what was left on presents for his friends: 880/4= 220
880-220=660
Of the money remaining, John put 4/11 into a checking account: 660*(4/11)=240
the last remaining $420 was left to charity: 660-240= 420

Answer:
<p=.001
Step-by-step explanation:
see attachment
> Factor the expression for the revenue
We are given that the revenue is the product of price and
number of units sold = x p. Given the equation of revenue we factor it:
R = 800 x – 0.25 x^2
Take out x from the equation:
R = x (800 – 0.25 x)
We see that this is now in the form x p
> Determine an expression for the price in terms of x
From the factored equation we can say that the price in
terms of x is:
<span>p = 800 – 0.25 x</span>
