55-30=25
So it is + 25 dimes
Answer:
20
Step-by-step explanation:
→ First find the value of x and y
x + y = 5
x - y = 4
→ Add the equations to cancel out the y's
2x = 9
→ Divide both sides by 2 to find the value of x
x = 4.5
→ Substitute x = 4.5 back into x - y = 4 to find the value of y
4.5 - y = 4
→ Minus 4.5 from both sides to isolate -y
-y = -0.5
→ Multiply everything by -1
y = 0.5
→ Substitute x = 4.5 and y = 0.5 into x² - y²
4.5² - 0.5² = 20.25 - 0.25 = 20
We have to check which of PEMDAS rules can be applied in this case. We have only ADDITION. In this case we can observe that addition is:
1. Associative
2. Commutative
3. has Additive property

Answer: The cost of goods sold= 5881.75
Step-by-step explanation:
Cost of available goods = 75x32.97 + 75x33.78 + 150x35.02= $10259.25
Units available= 150 + 75 + 75= 300
Sold units= 175
Ending inventory= 300-175=125
Value of ending inventory= 125x35.02= $4377.5
Cost of goods sold= cost of available goods – value of ending inventory
Cost of goods sold= 10259.25 – 4377.5= $5881.75
