Total savings in first 6 weeks :

  • [tex]6x[/tex]

Totally savings in second 6 weeks :

  • [tex]6(2x - 30)[/tex]

If she saved $ 213 in first 6 weeks, then

  • [tex]6x = 213[/tex]

  • [tex]x = \dfrac{213}{6} [/tex]

  • [tex]x = 35.5[/tex]

now, money saved in second week :

  • [tex]6(2x - 30)[/tex]

  • [tex]6((2 \times 35.5) - 30)[/tex]

  • [tex]6(71 - 30)[/tex]

  • [tex]6 \times 41[/tex]

  • [tex]244[/tex]

The money saved in total 12 weeks :

  • [tex]213 + 244[/tex]

  • [tex] \$457[/tex]
