Answer:
Step-by-step explanation:
So generally a geometric sequence can be defined as: 
which is the explicit form. The r, is what each previous term is being multiplied by to get the next value which is evident in the recursive form: 
. Knowing this we can take two values which are "next" to each other to find what r is. In this case I'll just is 1 and 1/4, given these two values we know that: 
, 1*r is just r... so what each term is being multiplied by is 1/4. So let's plug the values into the explicit formula: 
(I didn't put an a_1 value in front, since it's just 1... so it's a bit redundant). Anyways using this formula we simply plug in 5 as n into the equation to find the 5th term: 
7 : x = 2 : 3
- divide 7 by 2.
7/2 = 3.5
- this is the scale factor.
- now multiply this by 3.
3 X 3.5 = 10.5
so, x = 10.5
Answer:
Price for Senior Citizen = $7.61
Percent of the regular price = 85% off original
Step-by-step explanation:
Regular Price is $8.95
Seniors get 15% off of that. So, first we need to find 15% of 8.95 and then subtract it from 8.95.
To get percentage of a number, we first convert the percentage to decimal (by dividing by 100) and then multiply it with the number.
15% = 15/100 = 0.15
Fifteen Percent of 8.95 is:
0.15 * 8.95 = $1.3425
Senior Citizen Price = 8.95 - 1.3425 = $7.6075
Rounded to nearest cent = $7.61
How much is this as a percentage of original?
Simple, it is 15% off of the regular price, so this price is 100 - 15 = 85% of original price
