To solve for \( b \) in the equation:
\[ 3.76 = 2.4 + 2.5b \]
First, let's isolate the term with \( b \):
- Subtract \( 2.4 \) from both sides:
\[ 3.76 - 2.4 = 2.5b \]
- Calculate \( 3.76 - 2.4 \):
\[ 1.36 = 2.5b \]
- Now, divide both sides by \( 2.5 \) to solve for \( b \):
\[ b = \frac{1.36}{2.5} \]
- Perform the division:
\[ b = 0.544 \]
So, the value of \( b \) is \( 0.544 \).
