In this problem, we know that Harry saved $100 each week for 8 weeks. In other words, he saved a total amount of money:

We know that he earned $48 on his savings of $800, so for every $100 the interest (I) he earns is:

So, in conclusion Harry did earn $6 in interest for every $100
Slope = (9/2 + 1) / (-2 + 5/3)
11/2
= ----------
-1/3
= 11/2 (-3/1)
= -33/2
or
= -16.5
Answer is B: 150
write two equations
r+s=190
4r+3s=720
solve by substitution
the get r=150 s=40
