im pretty sure it's the first option.
Answer:
The largest monthly payment he can afford for the T.V set in order to be kept within a safe load of 20% is $156
Explanation:
Before we calculate, let us extract the key information from this question:-
*** David's monthly net income is $1,360
*** David pays a monthly rent of $450
*** He is paying off a student loan which costs him $116 per month.
*** He intends purchasing a new T.v set
*** We are simply required to determine the largest monthly payment that David can afford for the T.v set in order for him to be kept within a safe load of 20%.
In order to calculate the largest monthly payment that he can afford for the T.v set so as to be kept within a safe load of 20%, we will need to determine the actual amount that is twenty percent of his net income. If his net income is $1,360 then twenty percent of it is:
20/100 × 1360
= 27200/100
= $272
All we need to do now to find the largest monthly payment he can afford for the TV set is to subtract the student loan that he is paying off monthly ($116) from twenty percent of his net income ($272). That is:-
$272 - $116 = $156
Therefore the largest monthly payment that David can afford for the television set in order for his credit card payments and student loan to keep him within a safe debt load of 20% is $156.
X+(2x+1)=4
3x+1=4
x=1
1+y=4
y=3
(1,3)
if x is a regular cip of coffee and y is a large cup of coffee. the first part of the equation being the number of the cups of coffee and the second part expressing the price. using the method of substitution we solve for x in the first equation
x= 5-y
and then we solve for y
then we substitute the value found in the easiest equation which would be the first one and we solve for x
x + 2 = 5
x + 2 - 2 = 5 - 2
x = 3
so its 3 regular cups and 2 large
