Answer:
The expression to determine the total cost in dollars is [tex]y=25+0.75x[/tex].
Step-by-step explanation:
Given:
Service charge to make a photo book = $20
Cost per extra page = $0.75
Cost to ship the complete photo book = $5
We need to write expression to determine the total cost in dollars.
Solution:
Let the number of extra pages be denoted by 'x'.
Also Let the Total cost be denoted by 'y'.
Now we can say that;
Total cost will be equal to sum of Service charge to make a photo book and Cost per extra page multiplied by number of extra pages and Cost to ship the complete photo book.
framing in equation form we get;
[tex]y=20+0.75x+5\\\\y=25+0.75x[/tex]
Hence the expression to determine the total cost in dollars is [tex]y=25+0.75x[/tex].
