Slide3Snow is falling at a rate of
3 inches per hour.
Let
t represent your total snowaccumulation and let h represent the hours that pass.Write an equation to representthis situation.
3h = t
Slide4Which statement is true?
a. The total
accumulation depends on
the hours that pass.The hours depend on the total accumulation.Snow is falling at a rate of3 inches per hour.What is your independent variable?What is your dependent variable?EXPLAIN
Slide5A carwash generate a
profit
a $8.00 per car.
Let p represent the profit earnedand let c represent the cars washed.Write an equation to representthis situation.
8c = p
Slide6Which statement is true?
a. The
number of cars washed depends on the profit.
