Question

Let m = 3. Evaluate the expression: 4m + 10O 70O 420 22o 17

Answer 1

`\begin{gathered} \text{The given expression is,} \\ 4m+10 \end{gathered}`

The m=3, put in the above expression.

`\begin{gathered} =4m+10 \\ =4*3+10 \\ =12+10 \\ =22 \end{gathered}`

Thus, the answer is 22.

`\begin{gathered} (2) \\ \text{The per day cahrge is \$}25\text{ and setup cost is \$6.75.} \\ The\text{ expression for d days,} \\ 25d+6.75 \end{gathered}`

Now, cost for 7 days,

`\begin{gathered} =25*7+6.75 \\ =175+6.75 \\ =181.75 \end{gathered}`
