Answer: the number of shoppers on the first day is 125
Step-by-step explanation:
The number of shoppers is 20% more than the numbers of shoppers the day before. It means that the number of shoppers is increasing in geometric progression. The formula for determining the sum of n terms, Sn of a geometric sequence is expressed as
Sn = (ar^n - 1)/(r - 1)
Where
n represents the number of term in the sequence.
a represents the first term in the sequence.
r represents the common ratio.
From the information given,
r = 1 + 20/100 = 1.2
n = 4(first 4 days)
S4 = 671
Therefore, the expression for the first 4 days is
671 = (a × 1.2^(4) - 1)/1.2 - 1
671 = (a × 1.2^(4) - 1)/0.2
671 = 1.0736a/0.2
671 = 5.368a
a = 671/5.368
a = 125
Answer:
x=-3
Step-by-step explanation:
you first distribute -2 then add 6.2 to both sides of the equation the finnaly divide by -3.4 to both side then you will get x
(-2)1.7x+(-2)3.1`
-3.4x-6.2=4
+6.2 +6.2
-3.4x=10.2
-3.4x/-3.4= 10.2/-3.4
x=-3
Answer:
E. y = 2/3x
Step-by-step explanation:
You need to make an equation in slope-intercept form.
First, you need to find the slope. You can do this by taking two points and dividing the difference of the y's by the difference of the x's. I will use the first two points, but you can pick whichever points you want and still get the right answer. Also, the values in the left column will be x's, and the values in the right column will be y's.
8 - 2 = 6
12 - 3 = 9
6/9 = 2/3
The slope is 2/3. The only equation with this value is E.
