Find the amount in an account if 7,650 is invested at 9.15 percent compounded quarterly for 8 years and 6 months
storchak [24]

We have been given that in an account an amount of 7,650 is invested at 9.15 percent compounded quarterly for 8 years and 6 months.

We will use compound interest formula to find our answer.

A=Pcdot(1+\frac{r}{n}) ^{nT},

Where, P= principle amount, A= amount after T years, n= period of compounding and r = interest rate (decimal).

Let us substitute our given values in our formula.

A=7650(1+\frac{0.0915}{4} )^{(8.5\times4)}  

A=7650(1+0.022875)^{34}

A=7650(1.022875)^{34}  

A=7650\cdot 2.15758136398

A=16505.4974    

Therefore, after 8 years and 6 months our amount will be 16505.497.

There are 58 students enrolled in an art class. The day before the class begins, 10.3% of the students cancel. How many students
Sidana [21]
First, set up a proportion. 10.3% is the percentage of students who cancelled, but the question is asking for the students who are attending, so let’s use 89.7% to make it easier. The proportion would be x over 58 is equal to 89.7% over 100%. Multiply 58 by 89.7, giving you 5,202.6. Next, take 5,202.6 and divide it by 100. This should give you 52. 026, but it’s best to round this to 52. 52 students actually attend the art class, making this your final answer.
