Answer 1

Answer:

[x + (9 - 1) 25] = 300

$100

Step-by-step explanation:

Hallie's mother gave her a birthday check of $x to start a savings account.

She also plans to save $25 per month as well.

So, after 9 months Hallie has in her account $[x + (9 - 1) 25]

Therefore, from the given condition we can write that  

[x + (9 - 1) 25] = 300 ......... (1) (Answer)

⇒ x + 200 = 300

⇒ x = $100

So, the original check amount from Hallie's mother was $100. (Answer)
