Solution: The group choice should be bagels.
There are 7 people who approve of bagels, 3 people for fruit, 5 people for muffins, 6 people for donuts, and one for Captain Crunch. Since the most people approve of bagels, that is the winner.
To solve this equation, we first want to get the by itself, so add
4 to both sides. This gives
Solution: First, notice that I messed up the problem, somehow thinking that from January 1 to September 1 is 9 months, while it is only 8 months. So, I'll give the solution twice (and full credit if you used either 9 or 8 months).
Note that the rate is 4% per year, but the time period is in months. That means we have to remember to convert months to years, and that 4% is the same as 0.04. Since the amount of interest is given as principalratetime, we have
Since I have to pay back the original principal plus the interest, I must pay $1000 + $30, or a total of $1030.
Now, if the time period is 8 months instead of 9 as above, we have
Since I have to pay back the original principal plus the interest, I must pay $1000 + $26.66, or a total of $1026.66.
