How many packages of diapers can you buy with $40 if one package costs $8? (What is the unknown and what would be the equation?)

• n= # of diapers; 8n = 40
• n= # of packages; 8n = 40
• n= # of packages; 8 - n = 40
• n= # of packages; 8/n = 40

Last Friday Trevon had $29. Over the weekend he received some money for cleaning the attic. He now has $41. How much money did he receive? (What is the unknown and what would be the equation?)

• n=amount of $ Trevon received; 29 - n = 41
• n=# of days; 29 + n = 41
• n=amount of $ Trevon received; 29 + n = 41
• n=amount of $ Trevon received; 29 + n = 40
