Answer:
40
Step-by-step explanation:
Let n represent the integer. Then the increase can be written as ...
n + (-12) = 28
We can add 12 to both sides of this equation:
n + (-12) + (+12) = 28 +12
n + 0 = 40 . . . . . . -12 and 12 total to zero; 28 and 12 total to 40.
n = 40
The integer is 40.

We are required to find the total sum of money given the fraction
The total sum of money is $9
let
<em>Total sum of money</em> = x
<em>8 1/3 of x = $75</em>
8 1/3 × x = $75
25/3 × x = 75
25/3x = 75
Divide both sides by 25/3
x = 75 ÷ 25/3
x = 75 × 3/25
x = (75 × 3) / 25
x = 225 / 25
x = 9
Therefore, the total sum of money is $9
