For her cell phone service plan, Angel pays $32 a month plus $0.75 for each minute over the allowed minutes in her plan. Angel received a bill for $47 last month. Write the equation that matches the real-world situation.

• $0.75m + $32 = $47

• $0.75m - $32 = $47

• $32m + $0.75 = $47

Eight less than three times a number is equivalent to ten more than one and a half times the same number. 

• 3x - 8 = 0.5x + 10 
• 8 - 3x = 1.5x + 10 
• 3x - 8 = 1.5x + 10
• 8 - 3x = 0.5x + 10
