Easiest to set up an inequality:

45,000 + 0.15*1,500*x>=85,000
45,000 + 225x>=85000
225x>=40000
x>=1600/9, (177 is just less than this, so we'll go with 178) Choice C

Lets say she sales x items so her commission will be : x * 1500*15/100 = 225x
Salary difference is: 85000 - 45000 = 40000

So commission must at least be equal to salary difference i.e. x = 40000/225 = 178 (Approx).
Hence answer is C.

My Take -

let the number of sales be n.
as per question -

85000 <= 45000 + 0.15*1500*n
40000<= 225*n
177.78 <= n

Hence option C

Answer = C) 178

Deficit in new job = 85000 - 45000 = 40000

Sales commission per unit \(= 1500*\frac{15}{100} = 225\)

Minimum sales required \(= \frac{40000}{225} = \frac{1600}{9} = 177.7 \approx{178}\)

Let n represent the least number of sales she makes for the year. We can create the equation:

85,000 = 45,000 + 0.15(1,500n)

40,000 = 0.15(1,500n)

40,000 = 225n

177.78 = n

So she must make at least 178 sales.
