Answer:
The budget line will remain unchanged.
Step-by-step explanation:
A budget line helps in showing the possible combinations of two commodities.
We can find the slope of the budget line that is also called the price ratio between two things. If we get a straight line, we say the slope is constant.
Here in the question its given that the initial constraints are (3,15) with initial income of $60. Then the price increases and constraints become (6,30) with an increase in income up to $120.
Therefore, the budget line will not be affected and remain unchanged as each constraint is doubling and the slope will be constant.
Using arithmetic sequence concepts, it is found that the common difference is of 0.25.
<h3>What is an arithmetic sequence?</h3>
In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of an arithmetic sequence is given by:

In which
is the first term.
In this problem, we have that:

Hence:

9 = 8 + 4d
4d = 1.
d = 0.25.
The common difference is of 0.25.

Answer:
4/15
Step-by-step explanation:
How much you need pay?
65x(1-25%)
=65x75%
=65x0.75
=48.75
Your answer should be $48.75.
