Let’s try a few translations
The sum of a number and 12 is 16
x + 12 = 16
The quotient of 15 and a number is less
than 3
• 15/x <3
Use the translation to solve real
problems
• You make a long distance call that costs
$0.10 a minute. You spent $5.00. How
many minutes did you talk?
• Cost of call = $0.10 per minute
• $5.00 = $0.10x
• $0.10 $0.10
• 50 = x
• You talked 50 minutes
