Answer:
5 dollars
Step-by-step explanation:
Let's call the price of a package of pens n, and the cost of a box of paper r.
3n+r=26
2n+7r=49
Multiply the first equation by 7:
21n+7r=182
Subtract the second equation from the first:
19n=133
Divide both sides by 19 to isolate n:
n=7
Plug this back in to find the value of a box of paper:
3(7)+r=26
21+r=26
r=5
Hope this helps!
The answer is definitely C because the words are very dark and creepy.
To answer the question above, evaluate the number of cookies each of them placed on a tray. The calculations are shown below,
Ronny C1 = 0.15 x 20 = 3
Celina C2 = 3
Jack C3 = 0.30 x 20 = 6
Michelle C4 = 20 - (3 + 3 + 6) = 8
From the calculation above, <em>Michelle</em> placed the most number of brownies on the tray.
