Question

What is the value of s in the equation below?

0.3s + 0.8 (s − 12) = 33.3

A 4.29
B 34
C 39
D 41.2

Answer 1

0.3s + 0.8s − 9.6 = 33.3

1.1s = 33.3 + 9.6 = 42.9

s = 42.9/1.1 = ?

Answer 2

[AI-generated answer — Explain Bot]

To find the value of s in the equation 0.3s + 0.8 (s − 12) = 33.3, we can follow these steps:

Step 1: Distribute the 0.8 to the terms inside the parentheses:
0.3s + 0.8s - 9.6 = 33.3

Step 2: Combine like terms:
1.1s - 9.6 = 33.3

Step 3: Move -9.6 to the other side of the equation by adding 9.6 to both sides:
1.1s = 43.9

Step 4: Divide both sides by 1.1 to solve for s:
s = 43.9 / 1.1

Step 5: Calculate the value of s:
s = 39.9

Therefore, the value of s in the given equation is approximately 39.9.
The answer is C: 39.
