Question

There were (2b+3) baseball bats sold on Tuesday. There were (3b-8) softball bats sold. What is the total number of bats sold if b=4?

Answer 1

Let's calculate the expressions for the value of b = 4

First expression

`\begin{gathered} 2b+3 \\ 2(4)+3 \\ 8+3 \\ 11 \end{gathered}`

11 baseball bats sold on Tuesday

Second expression

`\begin{gathered} 3b-8 \\ 3(4)-8 \\ 12-8 \\ 4 \end{gathered}`

4 baseball bats sold

The total number of baseball bats is 4+11, therefore 15 baseball bats were sold in total.
