You are planning a party and need to know how many people you can invite for your party. You can only afford 1 pizza and it comes with 20 slices. You know that you can eat 1/5 of the pizza by yourself. Assuming your friends all eat the same amount of pizza as you, how many friends can you invite to your party?

The pizza you buy has 20 slices. When you eat 1/5 of the pizza, that means you eat 4 slices of pizza because 20*(1/5) = 4. This means there are 16 more slices of pizza. So, if each person eats 4 slices, then you can divide 16 by 4 and you get 4. This means you can invite 4 friends to your party!

Sam and Finn are deciding which person has the best pay for their job! Their pay can be modeled by a linear equation. Sam earns $10 per hour with a $50 signing bonus upfront for joining the company! Finn earns $20 per hour but does not earn a signing bonus upfront. Which person earns more money after 6 hours working?

Let x be the number of hours each of them work. Sam earns y = 10x + 50 Finn earns y = 20x + 0 We see that after 6 hours of working: Sam has earned y = 10(6)+50 = 60+50 = 110 Finn has earned y = 20(6) = 120 So, FINN has earned MORE money after working for 6 hours!
