Exhibition Scheduling Board: A city museum is allocating display-days to three guest art installations for the summer: Installations X, Y, and Z. The curators requested the following totals:
- Installation X: 180 display-days
- Installation Y: 105 display-days
- Installation Z: 60 display-days
The museum has 275 total display-days to award and will allocate all 275 days. Each installation must receive at most its requested total and at least 75% of its request. Display-day allocations are made in blocks of 15 days.
If none of the installations can receive its full requested number of display-days, select for Installation Y for the numbers of display-days the board could allocate to Installation Y, and for Installation Z for the numbers of display-days the board could allocate to Installation Z so that all constraints are satisfied.
Make only two selections, one in each column.
