Answer provided by our tutors
The text "high school musical 3 senior year" is ambiguous, unable to be certain about what 'musical 3' is intended to convey. We assume that each of the nieces received one gift and the '3' has no bearing on the DVD or CD soundtrack prices.
Let 'x' represent the number of nieces who received a DVD, then '5-x' represents the number of nieces who received the CD soundtrack, then:
70.51 = 14.99x + 13.88(5-x)
-------------------
-------------------
x=1
5-1=4
1 DVD was purchased and 4 CD soundtracks were purchased.
