The cost to rent a moving truck is a flat fee of $25 plus $0.60 per mile. The equation c = 25 + 0.6m models the cost, c, in doll
ars for the number of miles, m, traveled in the truck. Identify the independent and dependent variables.
what is the independent variable.
what is the dependent variable.
Lets begin with the Independent variable, C. C is moreover a result, so it remains as a dormant number that is yet to be known. M which is the dependent variable, contributes to the corresponding number we call the cost. When M , a quantity that is being manipulated the number 0.6, multiplies "per mile" plus 25. The actual expression is 25 + 0.6m, and the indpendent variable is known as the numerical coefficient.
You will pay $32 for a item with original price of $40 when discounted 20%. In this example, if you buy an item at $40 with 20% discount, you will pay 40 - 8 = 32 dollars.
