Answer
Mario and Luigi plan to buy a Nintendo Switch for $299.00. Nintendo Switch games cost $59.99 each. They plan to purchase one console. Use an algebraic expression to describe how much they will spend, before sales tax, based on purchasing the console and the number of games
Answer
If they purchase one console and three games, how much will they spend before sales tax?
Answer
Mario and Luigi want to purchase some extra controllers for their friends. Each controller costs $29.99. Use an algebraic expression to describe how much they will spend in total, before sales tax, based on purchasing the console, the number of games, and the number of extra controllers.
Answer

Answer
Use the diagram to answer the question.
The Hertzsprung-Russell Diagram is shown. The left y-axis is labeled luminosity and the right y-axis is labeled absolute magnitude. The bottom x-axis is labeled with temperature left parenthesis Kelvin right parenthesis. The temperatures along the bottom are 40,000, 20,000, 10,000, 7,500, 5,500, 4,500, and 3,000. The top x-axis is labeled spectral class. The spectral classes labeled along the top from left to right are O, B, A, F, G, K, and M. Spectral class O lines up with a temperature of 40,000 K. Spectral class B lines up with a temperature of 20,000 K. Spectral class A lines up with a temperature of 10,000 K. Spectral class F lines up with a temperature of 7,500 K. Spectral class G lines up with a temperature of 5,500 K. Spectral class K lines up with a temperature of 4,500 K. Spectral class M lines up with a temperature of 3,000 K. Stars of different luminosity, absolute magnitude, spectral classes, and temperatures are plotted on the graph. Red giants and supergiants are shown in the upper right quadrant, indicating lower temperatures. White dwarfs are shown in the lower left quadrant, indicating higher temperatures and lower luminosity. Different main sequence stars are shown, ranging from hot and bright in the upper left quadrant to cooler and dimmer in lower right quadrant.

Answer
Use the diagram to answer the question.
The Hertzsprung-Russell Diagram shows the spectral class of stars across the top, the temperature in Kellvin of stars across the bottom. The luminosity of stars, with the luminosity of the Sun equal to one, on the right, and the absolute magnitude of stars on the right. Blue giants, red supergiants, red giants, main sequence stars, the Sun, and white dwarfs are shown on the diagram.
