Assuming the inteest is annual, since it's simple that means we just have to analyze:
, where r is our interest rate as a decimal, t is time, p is our principal investment and A is our ending value. So, in the context of our problem this becomes:
, which when evaluated by our trusty calculator becomes:
7657.68938,
which is rounded to 7500 in the problem.
14:15 because there’s 14 circles plus one heart (14+1) and it’s circles (14) to shapes(15)
7/8+9/10=71/40=1 31/40
1/4+2/3=11/12
1/2+1/4 is different from 1/2+1/3 because
1/2+1/4= 2/4+1/4= 5/1 =1 1/4
1/2+1/3=3/6+2/6=5/6
So for this problem we are looking for a sum (total). So first we are going to round 25.65 to 25.7 and round 14.23 to 14.2
Now we are going to add 25.7 and 14.2 to get a total of 39.9
