Answer:
Cost of one roll of plain wrapping paper is $12 and Cost of one roll of holiday paper is $17.
Step-by-step explanation:
Solution,
Let the cost of 1 plain wrapping paper be x.
And the cost of 1 holiday paper be y.
Julie sold 13 rolls of plain wrapping paper and 8 rolls of holiday paper and earns $292.
Total Money earned by Julie is equal to sum of number of wrapping paper multiplied with cost of wrapping paper and number of holiday paper multiplied with cost of holiday paper.
So we can frame it in equation form as;
Now, Mark sold 7 rolls of plain wrapping paper and 2 rolls of holiday paper and earns $118.
Total Money earned by Mark is equal to sum of number of wrapping paper multiplied with cost of wrapping paper and number of holiday paper multiplied with cost of holiday paper.
So we can frame it in equation form as;
Now Multiplying equation 2 by 4 we get;
Now Subtracting equation 1 from equation 3.
Now substituting the value of x in equation 1 we get;
Hence Cost of one roll of plain wrapping paper is $12 and Cost of one roll of holiday paper is $17.
Answer:
Step-by-step explanation:
Let n = the number of prints
and C = the total cost.
At the regular price, the formula is
C = 1.45n
During the promotion, you must pay for the first nine prints: 9 × 1.45 = 13.05.
For anything over nine prints (n - 9), you must pay $13.05 plus the promotional cost of $1.10 for each print. The promotional formula is
C = 13.05 + 1.10(n - 9) {n > 9}
1. Calculate the cost of 19 prints
2. What number of the prints is a waste of money?
During the promotion, buying fewer than nine prints would be a waste of money, because you would not be taking advantage of the promotional savings.
