Answer:
7x + 3y </=8
Step-by-step explanation:
Let x represent the number of rides Beth rides and y represent the number of exhibits she views
Each ride costs $7 to ride and each exhibit costs $3 to view
This means that x rides will cost x × 7 = $7x
Also, if she views y exhibits, the cost will be y × 3 = $3y.
Total cost of x rides and y views will be 7x + 3y
if she has at most $98 to spend at the fair, it means that all she can spend must be lesser than or equal to $98
The required expression will be
7x + 3y </=8
