$x=213$

For first six weeks she saved 213$

Now

For next 6weeks

$\\ \sf\longmapsto 2x-30=2(213)-30=426-30=396\$$

Total savings:-

. $\\ \sf\longmapsto 396+213=609\$$

Total savings in first 6 weeks :

$6x$

Totally savings in second 6 weeks :

$6(2x - 30)$

If she saved $ 213 in first 6 weeks, then

$6x = 213$

$x = \dfrac{213}{6}$

$x = 35.5$

now, money saved in second week :

$6(2x - 30)$

$6((2 \times 35.5) - 30)$

$6(71 - 30)$

$6 \times 41$

$244$

The money saved in total 12 weeks :

$213 + 244$

$\$457$
