Solve by using a graph.
1. A carpet cleaner charges $25 per room cleaned. Predict the cost of
having 5 rooms cleaned.
2. The table shows the number of
packages contained in trucks.
Make a graph of the data and
use it to predict the number of
packages that can be transported in 5 trucks.
3. Use the graph that shows bagel prices.
What is the price of 2 dozen bagels?
