Answer:

Step-by-step explanation:
The formula ogf a volume of a pyramid:

B - area of a base
H - height
We have a base length a = 5 in and a height H = 9 in.
In the base we have a square. The formula of an area of a square is:

Substitute:

Calculate the volume:

Payment on Plan A = $300
x is the number of hours Jake works.
Payment on Plan B = Fixed charges + (charge per hour) × (number of hours worked)
= $150 + $6.25(x)
= 150 + 6.25x
Since, the payment on Plan B should be more than Plan A,
150 + 6.25x > 300
6.25x > 300 - 150
6.25x > 150

x > 24
The minimum vale for x which satisfies this inequality is 25.
Hence, x = 25.
