Answer:
Total cost of goods available for sale $800
Step-by-step explanation:
Total units available for sale = 100
Cost of per unit = $8
Total cost = Product of Number of units 
Cost of per unit
Cost of goods available for sale = 
Cost of goods available for sale =$800
Thus, We have total cost of good available for sale $800.
Let S = his average speed.
Let D = distance traveled one way
Time = distance / speed
Set up an equation:
d/6 + d/12 = 2d/S
Multiply the equation by 12s:
12s(d/6) + 12s(d/12) = 12s(2d/s)
Simplify to get:
2sd + sd = 24d
Combine like terms:
3sd = 24d
Divide both sides by d:
3s = 24
Divide both sides by 3:
s = 24/3
s = 8
His average speed was 8 mph.
Answer:
22
Step-by-step explanation:
Missy has 156 cards in total. Since we know she has 4 times as many as them, we divide 156 by 4
156/4= 39
Ashe has 17 cards and we still don't know how many Caleb has. Since we know that they have 39 cards together, we need to subtract Ashe's cards to find how many Caleb has
39-17=22
Let's check our work
Caleb has 22 cards
Ashe has 17 cards
Together they have 39
Which is 4 times less than how many cards Missy has
Missy has 156 cards
We are correct!
You would do 16 + 40 = (8 X 2) + (8 X 5) = 8(2 + 5)
Hope this helps best of luck :)
