The river will not reach a level of 7 ft. after 5 hours.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the height of the water level after x hours.
Since the river is 1 ft below its average water level and begins to rise by a constant rate of 1.5 ft per hour. Hence:
b = -1, m = 1.5. The equation becomes:
y = 1.5x - 1
To reach a level of 7 ft. That is y = 7:
7 = 1.5x - 1
1.5x = 8
x = 5.3 hours
The river will not reach a level of 7 ft. after 5 hours.

Step-by-step explanation:
The second day, she sold more.
We know 7/9 is about 0.777777777778
And 0.78 < 0.85
So the second day she sold more.
3/4 of 20...." of " means multiply
3/4(20) = 60/4 = 15 onion plants <=
