Answer: a=225 adult, s=200 student
Explanation: We need a system of equations to find how many of each ticket Marc sold and we can use 4s+5a=1925 and s+a=425.
If we isolate a, we will have a=425-s
If we plug this into the first equation, we will get 4s+2125-5s=1925
Solving for s gives us s=200.
To find a, we can do 425-200 to find that a=225.

Answer:
4 more pens
Step-by-step explanation:
Well, what do we know?
We know Sheila has:
6 pens
10 pencils
How many MORE pens does she need to make the number of pens <em>equal to </em>the number of pencils?
6 + x (x is the number of pens needed to EQUAL to 10)
6 + x = 10
x = 4
Sanity check:
6 + 4 = 10
Sheila needs 4 more pens to make the number of pens and pencils equivalent, or EQUAL TO each other.
