Twice the difference of a number and 3 equals 2 use the variable c for the unknown number.

Lesechka [4]

The number is 4

Step-by-step explanation:

First of all we have to convert the given statement in mathematical form.

Let c be the number then according to given statement

$2(c-3) = 2$

We have to isolate the variable in the equation

Dividing both sides by 2

$\frac{2(c-3)}{2} = \frac{2}{2}\\c-3 = 1$

Adding 3 on both sides

$c-3+3 = 1+3\\c = 4$

Hence,

The number is 4

Lady_Fox [76]

This is just solving percentages which is fairly easy! :)
To solve an equation like this, make all the percentages into decimals:

-.30
-.25

Now, take 750$ and multiply it by .30 = 225$
Do the same with .25 % = 187.50

Now add the two variables together, and subtract from 750 $

The author will take home = 337.5
