Answer 2

Answer: It would cost $17.70 to send 118 text messages

Step-by-step explanation:

\$1.35 ÷ \color{steelblue}{9}\text{ texts}=

$1.35÷9 texts=

\,\,\text{\color{indianred}{\$0.15} per text}

$0.15 per text

\color{indianred}{\$0.15}\text{ per text} × \color{seagreen}{118}\text{ texts}=

$0.15 per text×118 texts=

\,\,\text{\color{purple}{\$17.70} }

$17.70

\frac{\text{dollars}}{\text{texts}}=

texts

We don't know how many dollars for 118 texts- call it xx

1.35\cdot\color{seagreen}{118}=

1.35⋅118=

\,\,9\cdot\color{purple}{x}

9⋅x

159.3=

159.3=

\,\,9\color{purple}{x}

9x

\frac{159.3}{9}=

9

159.3

​  

=

\,\,\frac{9\color{purple}{x}}{9}

9

9x

​  

 

Undo multiplication by dividing both sides by 9

17.7=

17.7=

\,\,\color{purple}{x}
