Answer:
Option C. 42 would be correct.
Step-by-step explanation:
An accountant gets paid for each tax return she prepares = $150.00

More to earn = 6,750 - 450 = $6,300
For preparing 1 tax return she earns = $150.00
To earn $6,300 she must prepare = $6300 ÷ $150 = 42 tax returns
To reach her goal she must prepare 42 more tax returns. Option C.
