Karen used a birthday check her mother gave her to start a savings account. She plans to save $25 per month as well. After 8 months, Karen has $250. Write and solve a linear equation to find the original check
amount from Karen's mother.

Explanation:

Lets just say the amount her mom gave her is c

and the months is a

the equation would be

c + 25a = 250

we can plug in 8 for a, cause we know its been 8 months,

c + 25(8)= 250

then do the parentheses

c + 200 = 250

subtract the 200 to isolate the variable c

c = 50

then you get c = 50,

Karen's mom gave her a check for $50.

(why karen btw. i would never give $50 to a karen)

answer: y=4000x+14000
