Answer:
The equation to determine number of burger Janie bought is .
Step-by-step explanation:
Given:
Cost of soft drink = $1.50
Cost of each junior size of burger = $1.25
Total bill paid = $9.00
We need to write the equation to determine number of burger Janie bought.
Solution:
Let the number of burgers Janie bought be 'x'.
