Answer:
25 sq feet
Step-by-step explanation:
Length = 5 feet
Area = (Length)²
= 5²
= 25 sq feet
You could use the function:
f(x)=30+2x
100=30+2x
In which lets say he rode 3 rides. Plug in 3 for x.
100=30+2(3)
Then Multiply
100=30+6
Then combine 30 and 6 to get 36.
Then you can subtract 36 from 100 to get
$64 left over.
9000 if you don't allow numbers with leading zeros, such as 0,000.
10,000 if you do allow numbers with leading zeros.
