Answer:
Step-by-step explanation:
Each successive year, he
earned a 5% raise. It means that the salary is increasing in geometric progression. The formula for determining the nth term of a geometric progression is expressed as
Tn = ar^(n - 1)
Where
a represents the first term of the sequence(amount earned in the first year).
r represents the common ratio.
n represents the number of terms(years).
From the information given,
a = $32,000
r = 1 + 5/100 = 1.05
n = 20 years
The amount earned in his 20th year, T20 is
T20 = 32000 × 1.05^(20 - 1)
T20 = 32000 × 1.05^(19)
T20 = $80862.4
To determine the his total
earnings over the 20-year period, we would apply the formula for determining the sum of n terms, Sn of a geometric sequence which is expressed as
Sn = (ar^n - 1)/(r - 1)
Therefore, the sum of the first 20 terms, S20 is
S20 = (32000 × 1.05^(20) - 1)/1.05 - 1
S20 = (32000 × 1.653)/0.05
S20 = $1057920
Area = b*h and in some cases * 2 so you need to do this, 64*52 + 40*28= 4448 yd2
Answer:
-6 and -7
Step-by-step explanation:
Set up an equation: x+x+1=-13 2x=-14 x=-7. Since it is negative, you go down 1. -6 and -7 hope this helps plz mark brainliest if correct
Answer:
C.
Step-by-step explanation:
First, you'll have to find how much it costs for one bottle of juice.
Store A- 4/12= 0.33 So one bottle of juice costs 33 cents.
Store B- 6/18= 0.33 So one bottle of juice costs 33 cents.
Yes, the rates are equivalent because one bottle of juice costs the same from each store.
