a. 50
b. 45
c. 42
d. 48

Option C. 42 would be correct.

Step-by-step explanation:

An accountant gets paid for each tax return she prepares = $150.00

She has already prepared 3 tax and get paid == 150 × 3 = $450.00

Her goal is to earn = $6,750.00

She has already earned  = $450.00

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.
