Answer:
Comprehensive explanation:
Let's denote
x -----> the number of days
and
y ----> the remaining minutes for Yuson
We know that
The linear equation in slope-intercept form can be represented as

here
m indicates the slope
b represents the y-coordinate of the y-intercept (starting value)
In this scenario, we have
The slope is defined as
----> negative, as it indicates a decreasing function
----> initial value
substituting the values

1.8x-5.4=30 add 5.4 to each side
1.8x=35.4 divide every side by 1.8
x=354/18
x≈19.67
Thus, 20 would serve as a solid approximation for x.
