Answer 1

The expression to determine the total cost in dollars is
`y=25+0.75x`.

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;

`y=20+0.75x+5\\\\y=25+0.75x`

Hence the expression to determine the total cost in dollars is
`y=25+0.75x`.
