Answer:Let the two unknown numbers be x and y.
So, x-y=40 ........Equation 1
And 0.3(x)= 37.5/100 (y)
From equation 1, x=40+y
Now, multiply through by 100 in equation 2.
We have,
30x = 37.5 (y)
We can multiply through by 10 again,so that the number on the L.H.S becomes a whole number.
Therefore, we have
300x = 375 (y)
Put "x=40+y" in the equation above
That is, 300 (40+y) = 375 (y)
1200 + 300y = 375y
1200 = 375y - 300y
1200 = 75y
Divide both sides by 75 to get your y
Therefore, y =16
From equation 1, we had x= 40 + y
Therefore X = 40 + 16
X= 56
Therefore the two unknown numbers are 56 and 16 respectively.

Answer: Option(e) exist 123.50 is correct.
Step-by-step explanation:
James earns:
Product A: 15 × 35.75 = 536.25
Product B: 16 × 42.25 = 676
Total Earnings = 1212.25
Sally earns:
Product A: 25 × 35.75 = 893.75
Product B: 10 × 42.25 = 422.5
Total Earnings = 1316.25
Andre earns:
Product A: 18 × 35.75 = 643.5
Product B: 13 × 42.25 = 549.25
Total Earnings = 1192.75
Above calculation shows that Sally is the most profitable seller and Andre is the least profitable seller.
So, the difference between the most profitable seller i.e Sally (1316.25) and the least profitable seller i.e. Andre (1192.75) is 123.50.
Answer:
In math, number blocks are commonly used as models, where a small square equals 1, a long rectangle equals 10, and a large square equals 100. As models, blocks can be used for addition, subtraction, multiplication, and division. You can represent a problem given by using the correct models.
(2/5)^3=(2/5)*(2/5)*(2/5).
