Cost of tablet $315
monthly payments of $25
a. 315 - 25 = $290
b. After each payment, the amount owed decreases. Therefore, the balance decreases.
second part of this: write equation for calculating the amount owed a for any number of payments n $ $25(n-1) =a
I cant draw a graph on here for you, but as n increases, then a decreases
d. as n increases by 1, how does a change? Answer: A decreases by $25 each time n increases by one
e. He will need to make 12.6 payments
The correct option regarding whether the table represents a proportional relationship is:
The relationship is proportional because the ratio of m to k is constant.
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, the ratio of m to km is given as follows:
k = 11/17.699 = 26/41.834 = 34/54.706 = 0.6215.
Since the values are equal, the correct option is:
The relationship is proportional because the ratio of m to k is constant.

It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Answer: 60 years
Step-by-step explanation:
Let x denotes the age of Demochares .
Time he spent as a boy = 
Time he spent as a youth = 
Time he spent as a man= 
Time he spent in dotage= 13 years
As per given , we have the following equation:

[Take LCM]





Hence, he is 60 years old.
Step-by-step explanation:
Putting value of x
(8)2 + 3(8)
64 + 24
= 88
