Envision Solving Equations and Inequalities

Shaan bought a video game console and some games for $350. The video game console cost $200. Each game cost $25. Write an equation that represents how many games Shaan purchased.

• 350 + 25x = 200

• 200 + 25x = 350

• 200 + 25x > 350

• 200x + 25 = 350

Ainsley bought some shirts for her clothing store $15 each. She received $50 off her entire purchase and spent a total oof $400. Which equation shows how many shirts Ainsley purchased for her store?

• 15x + 50 = 400

• 15 - 50x = 400

• 15x - 50 = 400

• 50 - 15x = 400

Alexa started a race with a 50-meter head start. She ran at a rate of 6.25 meters per second. Which equation shows how many seconds it took Alexa to reach 200 meters past the starting line?

• 50 - 6.25x = 200

• 50x + 6.25 = 200

• 50 + 6.25x = 200

• 50x - 6.25 = 200
