Da ne
b. 3 books for $12 and 5 books for $18
Da ne
c. 1 kilometer for 0.5 liters of gas and 2 kilometers for 1 liter of gas
Da ne
d. 10 oranges for $5 and 15 oranges for $8
Da ne
3. Finding the Constant of Proportionality:
For the following scenarios, find the constant of proportionality (k) by dividing the dependent quantity by the independent quantity.
a. If 4 kg of fruit costs $8, what is the constant of proportionality?
k = $ / kg = _______
b. If 10 pages of printing cost $1.50, find k.
k = $ / pages = _______
4. Solving for a Missing Value:
In each situation, one value is missing. Use the concept of proportional relationships to solve for the missing number.
