Question

Solve for P: 0.4P + 0.1 = 1.15.
A. 3.125
B. 0.5
C. 2.625
D. 0.42

Answer 1

C. 2.625. To solve for P in the equation 0.4P + 0.1 = 1.15, subtract 0.1 from both sides and then divide both sides by 0.4. The value of P is 2.625.

Step-by-step explanation:

To solve for P in the equation 0.4P + 0.1 = 1.15, you need to isolate P. Start by subtracting 0.1 from both sides of the equation to get 0.4P = 1.05. Then, divide both sides by 0.4 to find the value of P. The equation becomes P = 1.05 / 0.4.

Simplifying the division gives you P = 2.625. Therefore, the correct answer is C. 2.625.
