Answer:
35 sq units
Step-by-step explanation:
The answer is the 4th option,
x+y=6 and x-y= -10
Area = length * width
Area = (n yds + 40 yds) * 30 yds
or
Area = (30 yds * n yards) + (30 yds * 40 yards)
This is if you add the area of the rides to the area of the arcade (the first parenthesis is the rides, the second is the arcade.)
The discount is $2.50, the new price would be $2.50. Unless you factor in sales tax.
