Let sales in June be $$S$$
As per the question stem Income = 2000 + 10%*(S-2500) . Hence to calculate earning we need the value of $$S$$

Statement 1: Income = 20% of S
this implies 20% of S = 2000 + 10%*(S-2500) . this is a linear equation with only one unknown value $$S$$, hence sufficient to find the value of S

Statement 2: Income = 15% of (S+ 17500)
this implies 15% of (S+ 17500) = 2000 + 10%*(S+17500-2500). a linear equation in $$S$$. Hence the value of $$S$$ can be found. Sufficient

Option $$D$$

Option D

$$2000 + (X - 2500) * 0.1 = ?$$

Stmt 1
$$2000 + (X - 2500) * 0.1 = 0.2X$$
1 equation 1 variable --> can be solved

Stmt 2
$$2000 + (X + 15000)* 0.1 = 0.15(X + 17500)$$
again, 1 equation 1 variable --> can be solved

(1) The amount that Allison earned in June was equal to 20% of her total sales for June.

(2) Had Allison sold \$17500 more than she did in June, her total earnings would have equaled 15% of her sales.

Monthly Salary, J = 2000 + 0.1(S - 2500)
J = ?

1) 2000 + 0.1(S - 2500) = 0.2S
=> 1750 = 0.1S
=> S = 17,500
We can find the earnings in June. Sufficient.

2) 2000 + 0.1(S - 2500 + 17500) = 0.15(S + 17500)
=> S = $$\frac{875}{0.05}$$
=> S = 17,500
We can find the earnings in June. Sufficient.

D is the answer.
