Answer:

5

Step-by-step explanation:

If we consider half the first purchase, it is

2 used + 1 new = $42

And the second purchase is

6 used + 1 new = $78

Subtracting the first of these equations from the second, we get ...

4 used = $(78 -42) = $36

used = $9 . . . . . . . . . . . . . . divide by 4

Then we can find the price of a new game from ...

new = $42 - 2 used = $42 -2·9 = $24

___

The number of used games Janet can purchase on her budget is ...

($120 -3·$24)/$9 = $48/$9 = 5 1/3 ≈ 5

Janet can purchase 5 used and 3 new video games for $120. (and have $3 left)
