anna saved $12,593 which was 70% of the amount she needed for a used car. what was the total amount she needed for the car?
Let's represent the total amount Anna needed for the car as "x".
We know that 70% of x is equal to $12,593.
To calculate 70% of x, we can multiply x by 70% to get:
0.70 * x = $12,593
Dividing both sides of the equation by 0.70 gives:
x = $12,593 / 0.70
Simplifying the right side gives:
x = $17,990
Therefore, the total amount Anna needed for the car was $17,990. Answer: \boxed{17990}.
