N/8 = 25/40
40n = 25 * 8
40n = 200
n = 200/40
n = 5

n/20 = 85/100
100n = 85 * 20
100n = 1700
n = 1700/100
n = 17

2/3 = 16/n
2n = 16 * 3
2n = 48
n = 48/2
n = 24

5/6 = 25/n
5n = 25 * 6
5n = 150
n = 150/5
n = 30

Henry charged $847 to his credit card . The card the cost of his next purchase caused him to go over his credit limit of $1000.

Answer:

(x-2 )( x + 1) = (-2 - c)

Step-by-step explanation:

C= - 1 = -x

We cna either multiply x and c until we find HCM before imputing x value and c value that is unknown variable.

To find that we can say x = the average of 1000 + $800 = $900 and work out the difference between the two.

We can use a new variable for half that difference to ensure we add or subtract to find the value 1000 or -1000 again.

So that $1000 - $847 = $153 half this difference is 2/3y so that 4/3 = $153 and 1/3 = 33.333 as we are working with 3 numbers then 1/3 or 2/3 for example could show a debit;

Balance of each 1000 would look like

2/3y + x + c

= c + xy - y1/3

to show smaller amounts for the last 2 debits.
