The exchange rate of U. S. Dollars ($) to Icelandic kr$\text{\'o}$nur (ISK) is $\$1.00 = 120\text{ ISK}$. On a trip to Reykjav$\text{\'\i}$k, Geri orders a meal for $2370\text{ ISK}$. What is the equivalent price in U. S. Dollars and cents? Enter your answer in the form $\$ab. Cd$, where $a, b, c,$ and $d$ are replaced by appropriate digits.

The equivalent price is $19.75.

Step-by-step explanation:

Given:

The exchange rate of U. S. Dollars ($) to Icelandic krona (ISK) is $1.00=120 ISK.

On a trip to Reykjavik, Geri orders a meal for 2370 ISK.

Now, to find the equivalent price in U. S. Dollars and cents.

As, the exchange rate is:

$1.00 = 120 ISK.

Geri orders a meal for = 2370 ISK.

Now, to find the equivalent price by using conversion factor:

Therefore, the equivalent price is $19.75.

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!
