PLEASE HELP! IM SO SLOW! I have two questions about this graph.

1. a computer program found that the line C=2t-89 is a good fit for the data. Please use this graph to predict how many cups of lemonade Lynn might sell on a day when the temperature is 74 degrees.

2. the high temperature this Sunday is expected to be 5 degrees warmer than the high temperature this Saturday. Using the line C=2t-89, how many more cups of lemonade should Lynn expect to sell on Sunday than Saturday.​

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
