Unit 5 STAAR Assessment Review

A customer at a store paid $20 for 3 large candles and 2 small candles. At the same store, a second customer

paid $5 more than the first customer for 1 large candle and 7 small candles. The price of each large candle is

the same, and the price of each small candle is the same. 

Which system

• 20=3y+2y

  20+5=7x+y

• 3x+2y=20

An exponential function is graphed on the grid.

Which function is best represented by the graph?

The graph shows the number of game consoles sold in millions since 2009.

Based on this information, write a function that best models the number of game consoles sold in millions x years since 2009.
