what is the final amount of 17.50 that is put into a saving account with 4 annual interest rate compounded yearly for 25 years?

pickupchik [31]

To find the total amount, you will use the formula for finding compounded interest. This means you will be paid interest on top of the interest you have earned each year.

A = P(1 + r)^nt
P stands for the principal.
r is the interest rate when compounded annually
nt is the number of years

A = 17.50(1 + 0.04)^25
A = $46.65

This person would have $46.65 after 25 years.

Out of the 150 students at a summer camp, 72 signed up for canoeing. there were 23 students who signed up for trekking, and 13 o

True [87]

Answer:

Approximately 45% students signed up for neither canoeing or trekking.

Step-by-step explanation:

First we subtract the number of the students who signed up from the number of the total students to find the number of the students who did not signed up for either.

But there are 13 students who signed up canoeing and also for trekking.

Hence the number of students they signed up for activity is

72 + 23 - 13 = 82

And the number of students they not signed up for any activity is

150 - 82 = 68

so 68 students signed up neither for trekking nor canoeing. The percentage of those students are :

$\frac{68}{150}$ × 100 = 45.3333%

Approximately 45% students signed up for neither canoeing or trekking.
