Answer 1

Answer:

The price for 17 minutes of phone call is;

$\text{ \ 3.40}$

Explanation:

Given that the price of a 7 minute phone call is 1.40.

$\begin{gathered} 7\text{ minutes }\rightarrow\text{ \ 1.40 } \\ \text{divide through by 7;} \\ \frac{7}{7}\text{ minutes }\rightarrow\text{ }\frac{\text{\ 1.40 }}{7} \\ 1\text{ minutes }\rightarrow\text{ \ 0.20 } \end{gathered}$

For 17 minutes phone call the price can be calculated as;

$\begin{gathered} 1\text{ minutes }\rightarrow\text{ \ 0.20 } \\ \text{ multiply both sides by 17;} \\ 17\text{ minutes }\rightarrow\text{ \ 0.20 }\times17 \\ 17\text{ minutes }\rightarrow\text{ \ 3.40 } \end{gathered}$

Therefore, the price for 17 minutes of phone call is;

$\text{ \ 3.40}$
