A.) If Grace and Claire’s parents each invested $7,600 into a college savings account when the girls were born, how much money will each girl have for college when she turns 18? Explain.
Answer/Explanation:
For Grace, I plugged in 18 for x.
Work:
y= 1000(18) + 7600
y= 18000 = 7600
y= 25600
For Claire, I had to first find the slop by using rise over run.
11600-10000/3= 800
So the formula for Claire is y= 800x + 7600 and then you just plug in 18 for x.
Work:
y= 800(18) + 7600
y= 14,400 + 7600
y= 22,000
Therefore, Grace would have $25,600 at the end of 18 years old and Claire would have $22,000 when she turns 18 years old.
I hope that helped you or anyone else!! :)
