The registration for new members of a gym is $ 1.
The gym payment per day is $ 1.
The equation that models this problem is:
y = x + 1
Where,
x: is the number of training days
y: it is the total payment
The intersection with the y axis (1) represents the cost of the inscription.
The slope of the line (1) represents the daily payment.
<u>Answer:</u> n=31
<u>Reasoning:</u> -8+n=23
First add 8 to both sides (-8+8 and 23+8)
n=31
