Answer:
She needs to make nearly 60 sales to earn $2000
Step-by-step explanation:
Initial amount = 120
Every increasing sale = 31.5
Number of sales = x
Total amount = 2000
=> 31.5x + 120 = 2000
=> 31.5x + 120 - 120 = 2000 - 120
=> 31.5x = 1880
=> 31.5x/31.5 = 1880/31.5
=> x = 59.6825396825
=> x is nearly 60
