Answer :
Hello
The cost of the game is $180 and he makes an average of $6 weekly
Let x represent the number of weeks it will take him to save it up
[tex]\begin{gathered} 1\text{ w}eek=6 \\ x=180 \end{gathered}[/tex]Step 2
Cross multiply both sides and make x the subject of formula
[tex]\begin{gathered} 6\times x=1\times180 \\ 6x=180 \end{gathered}[/tex]step 3
divide both sides by the coefficient of x
[tex]\begin{gathered} \frac{6x}{6}=\frac{180}{6} \\ x=30 \end{gathered}[/tex]From the calculations above, it will take Nolan 30 weeks to save up for the game. This corresponds to option B
