Answer: 
Answer:
see below
Step-by-step explanation:
The sum of an infinite series with first term "a" and common ratio "r" is ...
S = a/(1 -r) . . . . . for |r| < 1
Then the sums for the given answer choices are ...
A: 5/(1 -3/4) = 20 . . . . . the answer of choice
B: 4/(1 -5/6) = 24
C: 4/(1 -1/5) = 5
D: 10/(1 -1/5) = 12.5
B) 35x + 15 = 155
E) It will take 4 months to pay off the debt.
Hope this helps you!
It's 5.4- I just used the calculator on my phone but I would've just done long division if I didn't have a calculator
Aaron the car wash owner had 228 quarters and 120 dimes.
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more variables and numbers.
Let x represent the number of quarters and y represent the number of dimes. Hence:
x = 90% of y + y
x = (0.9y) + y
x - 1.9y = 0 (1)
Also:
0.25x + 0.1y = 69 (2)
From both equations:
x = 228, y = 120
Aaron the car wash owner had 228 quarters and 120 dimes.
