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?

• 7.SP.4Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations.

Mathematical Practices1 Make sense of problems and persevere in solving them.3 Construct viable arguments and critique the reasoning of others.4 Model with mathematics.6 Attend to precision.
