For Part B
Here's another kind of pressure problem. A force of 22 pounds presses on a membrane. The average pressure on the
membrane is 2.75 pounds per square inch (psi). What is the area of the membrane in square inches? The equation for
calculating pressure is P= where Pis pressure, Fis force, and A is area.
F= 22 lb.
ents
A = ? sq.in.

8 in^2.

Step-by-step explanation:

F = P * A

22 = 2.75 * A

A = 22/ 2.75

A = 8 in^2.

The sale price is $1

$1 is not a better price since there is a cheaper price of $0.7

Step-by-step explanation:

Original price is $2

The price now is 0.5 × $2 = $1

If the sale price was 0.35 of the original price;

It would be 0.35 × $2 = $0.7

$1 is not a better price since there is a cheaper price of $0.7
