Answer:
Amount paid for the sheets of wrapping paper is [tex]7 \times 3m[/tex]
Step-by-step explanation:
Given:
Cost of gift tag = m cents
Cost of wrapping paper = thrice as much as gift tag
Total cost paid for 7 gift tags and wrapping paper = $12
To Find:
Amount paid for the sheets of wrapping paper = ?
Solution
The cost of gift bag = m
The cost of wrapping paper = 3m
Now the cost of 7 gift bags and wrapping paper is $12[tex](7 \times =>\text{cost of one gift bag})+ (7 \times \text{cost of one wrapping paper} )= 12[/tex]
=>7m + 7(3m) = 12
=>7m +21m =12
=>28m = 12
=> [tex]m = \frac{12}{28}[/tex]
=> m = 0.428 cents
Now the cost of one wrapping paper
=> 3m
=> 3(0.428)
=>1.284 cents
Cost of 7 wrapping paper
=> [tex]7 \times 3m[/tex]
=> 7 X 1.284
=>8.988
=>9 cents
