Answer:
The annual interest rate is 12.05%.
Step-by-step explanation:
The simple interest is given by the formula:

Where I denotes interest.
P denotes the principal amount.
R denotes the rate of interest
and T denotes the time period.
I=$160.67, P=$2000, t=8 months=8/12 years (Since 12 months=1 year so 1 month=1/12 year)

Hence, the annual interest rate is 12.05%.
Z=7 all you really gotta do is subtract 12 from 19 and you get 7
(x)1100+(y)113 x depends on the amount of computers is sold so x will change. y will be the amount of hard drives sold and then you add the total amount together.
