You are considering making a major purchase on your credit card. you should ask yourself the following questions, except which answer choice? a. would it cost me less if i came up with a different purchasing plan? b. what else can i purchase to reach my full credit limit? c. will i receive any incentives from my credit card company for making this purchase? d. how much will my purchase really end up costing if i don’t pay off the balance immediately?

The correct answer is option B definitely.

Step-by-step explanation:

When we are purchasing something from credit card, the first thing that comes to the mind is when will I be able to pay back the entire amount. The second thing is, we always think of reward point or incentives while making any purchase. We also think of secondary options where we can save money. But what to purchase to reach the full credit limit is definitely something no one ever thinks.

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!
