Answer: she will make $232.05 in 4 weeks.
Step-by-step explanation:
Since her profit is increasing by 10% each week, then the rate at which it is increasing is in geometric progression. The common ratio, r would be 110/100 = 1.1
We would apply the formula for determining the sum of n terms of a geometric progression which is expressed as
Sn = a(r^n - 1)/(r - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms(number of weeks)
From the information given,
a = 50
r = 1.1
n = 4 weeks
Therefore,
S4 = 50(1.1^4 - 1)/(1.1 - 1)
S4 = 50(1.1^4 - 1)/0.1
S4 = $232.05
1/4 or .25 or 25%
You basically just divide 60 by 15. So 15 goes into 60 4 times. Therefore, 4 is our denominator with one as our numerator.
The multiplicative rate of change for the exponential change is 3
Set a y equation or x equation
x-2y=3
x= 2y+3
plug in the x equation to the other equation
4x-8y=12
4 (2y+3)-8y=12
8y + 12 -8y=12
0=0?? I think this means y=0
plug in the y value to the x equation
x= 2 (0) +3
x= 3
points (3,0)
