Answer: Total cost at Aqua town = 4.50+0.75x
Total cost at Splash world = 2.50+1.25x
Step-by-step explanation:
Total cost = Admission charge + Charge per ride x Number of rides
Let x= Number of rides.
Aqua town charges 4.50 admission plus 0.75 for each ride.
Total cost at Aqua town = 4.50+0.75x
Splash world is 2.50 admission plus 1.25 per ride.
Total cost at Splash world = 2.50+1.25x
The required expressions:
Total cost at Aqua town = 4.50+0.75x
Total cost at Splash world = 2.50+1.25x
Since it's a square it must have 4 sides.
20÷4=5
area=l×w or b×h
5×5=25 (the sides of a square have the same length)
the area of the photograph is 25in²
hope this helped
