Answer:
$18,500
Explanation:
Let x represent the total cost of the car.
We have been given that Anna saved $12,950 which was 70% of the amount she needed for a used car. We can represent this information in an equation as:
![70\%\text{ of }x=\$12,950](https://img.qammunity.org/2019/formulas/mathematics/middle-school/cwyvniob3hriithrd2u64vbnpacphavex3.png)
![(70)/(100)x=\$12,950](https://img.qammunity.org/2019/formulas/mathematics/middle-school/81sy5023y9njgh1ux7wimeo04g5fz4m4hg.png)
![0.70x=\$12,950](https://img.qammunity.org/2019/formulas/mathematics/middle-school/ehg2954z8e4iq0g14qwt9cmwn8pd3zwngp.png)
![(0.70x)/(0.70)=(\$12,950)/(0.70)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/4fxr1w8efv9xusm6sng3tjub31lgpudtdn.png)
![x=\$18,500](https://img.qammunity.org/2019/formulas/mathematics/middle-school/lf7bmixn40pbz2p4t901ilfsd5cz7jce3u.png)
Therefore, the total amount needed for the car is $18,500.
