Answer:
y=3x-(-2,-13)
Step-by-step explanation:
He had put in $300 and got out $336 at the end of the year.
This means an increase of $36 over a year.
10% of $300 = $30 dollars
This shows that he definitely got more than a 10% increase.
Alan got $6 more than $30 so to find 6 from 30, you divide by 5
so ( 10% = $30 ) divided by 5 = ( 2% = $6 )
Adding the amount of money and percentages gives you 12% = $36
So the amount of mpercentage increase is 12%
Overall the amount of money in his bank now compared to when he deposited it, he has 112% in the bank.
