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!

1 sq units would be 1 mile, so 4 units are 4 miles. A little bit more than 4 is 6.
I know for 2x you would go up 2 over 1 but I don’t know about -7?? Maybe down
The answer is A because 75 + 15 is 90
