The amount in the account after the daily deposit for 5 days is $5
<h3>How to determine the amount in the account?</h3>
The given parameters i the question are represented as follows
Initial balance = -$30
Daily deposit = $7
Number of days of deposit = 5
The equation that represents the amount in the account is represented as
Amount = Initial balance + Daily deposit * Number of days
Substitute the known values in the above equation So, we have the following equation
Amount = -30 + 7 * 5
Evaluate
Amount = 5
Hence, the amount is $5

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.<span>(<span><span>−∞</span>,∞</span>)</span><span>{<span>q|q∈R}</span></span>
Because taking an absolute value of a number means making positive, then we can conclude that the absolute value of both numbers are 8.
|-8| = 8
|8| = 8
So he spent 1600 so x will represent original savings so
x-1600
then he spent 2/5 of the remainder on a refrigerator so
[(x-1600)2]/5
he had 1/3 of original savings left
[(x-1600)2]/5=1/3x
distrubute
(2x-3200)/5=1/3x
multiply both sides by 15
3(2x-3200)=5x
distrubute
6x-9600=5x
subtract 5x from both sides
x-9600=0
add 9600 to both sides
x=9600
