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.
Solution:
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.
