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
![\begin{gathered} 1\text{ w}eek=6 \\ x=180 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/o5rn4asyxeravt4t6lxx8h7jitmu9bzu15.png)
Step 2
Cross multiply both sides and make x the subject of formula
![\begin{gathered} 6* x=1*180 \\ 6x=180 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/u0bnjh2gdcwokktuxj1gxumayxmny2w0em.png)
step 3
divide both sides by the coefficient of x
![\begin{gathered} (6x)/(6)=(180)/(6) \\ x=30 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/rs54pzl6d3dicps7wuhdm5nqpqsqkbfn00.png)
From the calculations above, it will take Nolan 30 weeks to save up for the game. This corresponds to option B
