see below
Step-by-step explanation:
The independent variable is the variable that gets changed and the dependent variable relies on the independent variable
F.If you get pulled over for speeding, the ticket will cost $50 for each mile over the speed limit.
The independent variable is the miles over the speed limit, and the dependent is the cost
The cost relies on the number of miles over the speed limit
G.You are starting a garden and already bought the pots for $25.
Each flower you buy costs $3.50
The independent is the number of flowers purchased, the total cost is the dependent
The cost is dependent on the number of flowers purchased
H.Your grandmother is knitting you a blanket. She already made the blanket 5 inches long. Each hour she knits, the blanket gets 0.8 inches longer.
The independent is the hours knitted, the dependent is the length of the blanket
The length will depend on how long she knits
I.You are washing cars for a fundraiser. You make$10 for each car washed.
The number of cars is the independent variable and the dependent variable is how much money you make
How much you make depends on how many cars you wash
