Independent vs Dependent Variables Algebra

Zach and his friends are at an arcade and are redeeming their tickets for prizes. The number of prizes they can get is calculated based on how many tickets they have won.

p = the number of prizes the friends can get

t = the number of tickets the friends have won

• t is the independent variable and p is the dependent variable

• p is the independent variable and t is the dependent variable

Dan is wrapping gifts to earn money for camp. He calculates the amount of wrapping paper he needs based on the number of gifts.

r = the number of rolls of wrapping paper

g = the number of gifts

• g is the independent variable and r is the dependent variable

• r is the independent variable and g is the dependent variable

Allen is buying birthday candles for his grandmother's birthday cake. Her age, in years, will determine how many boxes of candles Allen will purchase.

y = Allen's grandmother's age, in years

b = how many boxes of candles Allen will purchase

• b is the independent variable and y is the dependent variable

• y is the independent variable and b is the dependent variable

Belle manages the Hancock Orchard, which produces many different types of fruit, including pears. The more pear trees that have been planted in the orchard, the more barrels of pears the orchard will produce.

p = the number of pear trees that have been planted in the orchard
b = the number of barrels of pears the orchard will produce

• p is the independent variable and b is the dependent

• b is the independent variable and p is the dependent
