Answer:
Step-by-step explanation:
Step one:
given data
Maya
P=$1650
r=5%= 0.05
t= 4 years
The simple interest expression is
A=P(1+rt)
A=1650(1+0.08*4)
A=1650(1+0.32)
A=1650(1.32)
A=1650*1.32
A=$2178
James
P=$1600
r=8%= 0.08
t=4years
The compound interest expression is
A=P(1+r)^t
A=1600(1+0.08)^4
A=1600(1.08)^4
A=1600*1.360
A=$2176
<em>After 4 years Mayas' balance is $2178</em>
<em>After 4 years James' balance is $2176</em>
<em>the difference is =2178-2176=$2</em>
Answer:
36
Step-by-step explanation:
it is given that there are total of 80 students
in German language there are 25 students
in French language there are 15 students
13 studying Spanish language
in German and French language there are 3 students
in French and Spanish language there are 4 students
in German and Spanish language there are 2 students
3 are studying all three languages
from the given bellow ven diagram
it is clear that the number of students that are not studying any languages are =80- (20+3+8+4+2+7)=36
The easiest way is to just solve the equation.
4x - 4 = -4x + 60
4x + 4x = 4 + 60
8x = 64
x = 8
A slower way to do this is to plug each of the numbers into the equation to see which makes the equation is true.
So for A.
4(8 - 1) = -4(8) + 60
4(7) = -32 + 60
28 = 28
Fortunately, this is true, so A is the answer and you don't have to try the other options.
