The number of white sweatshirts is 28
Step-by-step explanation:
Let ordered black shirts be represented by b
Let ordered white shirts be represented by w
So total sweatshirts will be represented by the equation
b+w=50
The total cost of the ordered sweatshirts will be represented by
10b + 12 w= $556
For simultaneous equations as;
b+w=50
10b+12w=556
solving the equations using substitution method where b=50-w
10(50-w)+12w=556
500-10w+12w=556
-10w+12w=556-500
2w=56
w=56/2= 28
b=50-w=50-28=24

7x-y=9
3x-y=5 (multiply by -1 both sides of the equation)
7x-y=9
-3x+y=-5 (now add both equations)
7x-3x-y+y=4
4x=4 (divide by 4 both sides of the equation)
x=1
y=3x-5=3×1-5=-2
y= -2
answer: x=1, y=-2
Answer: The answer is (b) Mary increased both assets and liabilities.
Step-by-step explanation: Given that Mary is going to buy a boat worth $30,000 with the help of a loan but she had $2000 cash to put down.
As a result, Mary took the loan for $28,000 to buy the boat. This will add one more number to the number of Mary's assets and also add one more number to the number of liabilities Mary has.
Therefore, after this purchase, the number of assets and the number of liabilities will both increase for Mary.
Thus, the correct option is (b) Mary increased both assets and liabilities.
