Answer:
hmm I don't remember it now hehe I'm sorry
Let the prior percentage be 
If we add 11.7% to
, we get 51.3%.
That is
.
This is a linear equation in
, so we solve for x to obtain,


Therefore the prior percentage was 39.6%
If 7m-3=53, them 7m=53+3
7m = 56, so m = 8.
Plug this into the other equation, 11m+2.
11(8) + 2 = 88 + 2 = 90
Answer:
The answer is 387. Let's see why.
Step-by-step explanation:
The computer costs $1548. And all the 12 payments are <u>equal.</u>
To find one payment we need to divide the total cost to the number of payments.

Each one of the payments is $129.
To find three payment we simply follow:
129 . 3 = <u>387</u>
Another solution can be;
Since we are looking for 3 of the payments we can divide it to the total payment
which equals to 
And we can find the answer by multiplying it with the cost which gives;
