ANSWER
50,000 + 100x = 75,000
STEP-BY-STEP EXPLANATION:
Given parameters
• Ed base salary = $50, 000
,• Commission on each computer sells = $100
,• Total income = $75,000
Let x be the number of computers sold
Total income = base salary + commission * number of cars sold
75000 = 50000 + 100* x
50,000 + 100x = 75, 000
Hence, the equation that can be used to find the number of cars sold is
50,000 + 100x = 75,000
