How much money should be invested every year with 4% interest per year in order to save up $26,000 in 18 years?

Answers

Answer:

$15116.28

Step-by-step explanation:

Given data:

interest rate, r= 4%

time, t= 18 years

Final investment, A= $26000

Principle investment, P=?

As per the formula of interest

A= P (1+rt)

26000= P(1+ 0.04(18))

P= 26000/(1+ 0.04(18))

P= 15116.28 !

How many cookies could you make with four cups of flour

Answers

Hi there!


Usually, the amount of flour varies between different cookie recipe's, but if you're going to make the normal chocolate chip cookie, into a batch of 60, you'd need 4 cups of flour.


So, 4 cups of flour would make your 60 chocolate chip cookies.


Hope this helps! :D

Please message me if you need anything else!
a bunch, but that depends on how much flour one batch needs

the blue lake trail is 11 3/8 miles long. Gemma has hiked 2 1/2 miles each hour for 3 hours . how far is she from the end of the trail

Answers

It is very important to look at all the information's that are given in the question. Based on those given information's the answer to the question can be easily deduced.
Length of the blue lake trail = 11 3/8 miles
                                            = 91/8 miles
Distance hiked by Gemma per hour = 2 1/2 miles
                                                          = 5/2 miles
Then
Distance hiked by Gemma in 3 hours = (5/2) * 3 miles
                                                             = 15/2 miles
Then
Distance from the end of the trail = (91/8) - (15/2) miles
                                                    = (91 - 60)/8 miles
                                                    = 31/8 miles
                                                    = 3 7/8 miles
So it can be concluded from the above deduction that the distance that is still left for Gemma to cover the trail is 3 7/8 miles. I hope there is nothing complicated in the procedure for you to not understand.
