Answer:
[tex]98w+115(13-w)\\[/tex]
Step-by-step explanation:
Given:
Gina takes classes at both West side Community College and Pinewood Community College.
At West side, class fees are $ 98 per credit hour,
At Pinewood, class fees are $ 115 per credit hour.
Gina is taking a combined total of 13 credit hours at the two schools.
At West side she is taking w credit hours.
Question asked:
What is an expression for the combined total dollar amount she paid for her class fees?
Solution:
Given that at West side, she is taking number of credit hours = [tex]w[/tex]
As combined credit hour is 13,
Then, at Pinewood, class, she is taking number of credit hours = [tex]13-w[/tex]
Now, we will find total amount she paid for [tex]w[/tex] number of classes at West side Community College, by unitary method:
She paid for 1 credit hour, Â = $98
She paid for [tex]w[/tex] credit hour = [tex]98w[/tex]
Thus, total amount she paid for [tex]w[/tex] number of classes at West side Community College is [tex]98w[/tex]
Similarly, we will find total amount she paid for [tex]13-w[/tex] number of classes at Pinewood Community College, by unitary method:
She paid for 1 credit hour = $115
She paid for [tex]13-w[/tex] credit hour = [tex]115(13-w)[/tex]
Thus, total amount she paid for [tex]13-w[/tex] number of classes at Pinewood Community College is [tex]115(13-w)[/tex]
The expression for the combined total dollar amount she paid for her classes:-
[tex]98w+115(13-w)\\[/tex]
