Answer:
The correct answer is: She bought 2 dress shirts and 5 t-shirts
Step-by-step explanation:
Let's marked dress shirts with x and t-shirts with y.
Now we will make equations to solve this problem:
x + y = 7 => y = 7 - x
40 x + 8 y = 120
When we replace y = (7 - x) in the previous equation we get:
40 x + 8 (7 -x) = 120 40 x + 56 - 8 x = 120 => 32 x = 120 - 56 =>
32 x = 64 => x = 64/32 = 2 => x = 2
y = 7 - x = 7 - 2 = 5 => y = 5
x = 2 dress shirts
y = 5 t-shirts

Step by step explanation is given in the image
The salary plus commission employee earned $3,500 in January. Let his amount of sales for the month of January be x, then $2,000 + 3% of x = $3,500.
0.03x = $3,500 - $2,000 = $1,500
x = $1,500 / 0.03 = $50,000
The straight commission employee earned $3,850 in January. Let his amount of sales for the month of January be y, then 7% of y = $3,850.
0.07y = $3,850
y = $3,850 / 0.07 = $55,000
The graduated commission employee earned $3,600 in January. Let his amount of sales for the month of January be z, then 5% of $40,000 + 8% of z = $3,600.
0.05 x 40,000 + 0.08z = $3,600
$2,000 + 0.08z = $3,600
0.08z = $3,600 - $2,000 = $1,600
z = $1,600 / 0.08 = $20,000
Total sales for the graduated commission employee<span> = $40,000 + $20,000 = $60,000
Therefore, the graduated commission employee had the largest dollar amount in sales of $60,000 for the month of January</span>
