Answer:
12 months.
Step-by-step explanation:
Samantha already has $2500 of the $7000 she needs, so we can just subtract that from the total.
7000 - 2500 = 4500
Samantha is saving $400 a month, and the total cost (minus the money she already has) would be $4500.
Now we can just divide $4500 by $400, which is 11.25
Rounded to the nearest whole number, we get 11 months.
However, to afford the car, she would need to save for at least 12 months.
If she saves for 12 months, she will have $4800. Though this is $300 more than she needs, if she saves for 11 months, she will only have $4400, which is not enough money to buy the car.
I hope this helps! (I would appreciate brainliest, if not that's okay!)
