Answer:
The expression to determine the total cost in dollars is .
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;
Hence the expression to determine the total cost in dollars is .
Answer:
3x=21
X=7
Step-by-step explanation:
Answer:
a. (5x-2)-(2x+1)
b. 3x-3
c.39
Step-by-step explanation:
To find the answer, turn the appreciated percent into a decimal:
5% ----> .05 (Divide by 100)
Then multiply it by the total value:
100,000 x .05 = 5000
Then add that to the total:
105,000
So the house is worth a total of $105,000.
Hope this helps!
