Answer:
5.65, I don't know what unit is needed or if it should be rounded
There started with 50 and it doubles so that means:
100 at the end of year 1
200 at the end of year 2
400 at the end of year 3
800 at the end of year 4
In this question there is a simple trick that needs to be handled first. Baring that simple trick the problem is very easy. The first thing that needs to be done after noting down all the details from the given question is to covert 1 hour to 60 minutes.
Time taken by Carla to travel 5 miles = 1 hour
= ( 1 * 60 ) minutes
= 60 minutes
Then
In 60 minutes the distance covered by Carla = 5 miles.
NOw
In 15 minutes the distance traveled by Carla = (5/60) * 15 miles
= 5/4 miles
= 1.25 miles
So Carla will travel a distance of 1.25 miles in 15 minutes.
A idk if that right but I slow so
Y = 11.5x + 22
y = -13x + 218
when will their balance be the same.....ur basically just subbing in 1 y for the other and u get :
11.5x + 22 = -13x + 218....now we solve for x
11.5x + 13x = 218 - 22
24.5x = 196
x = 196 / 24.5
x = 8 <== they will be the same at 8 weeks
11.5(8) + 22 = 114
-13(8) + 218 = 114
and they will both have $ 114 at 8 weeks <===
