Hello!
We use formulas to find the areas of different shapes. The formula for the area of a triangle is:
1/2 bh
These means that you must multiply the base by the height and then divide it by two.
Good Day!
From Walmart, you have to buy at-least= 50/8 = 6.25 = 7 [round-off to larger direction value ]
So, it would cost = 7 * 2.99 = $20.93
From Sam's club, you have to buy at-least= 50/12 = 4.16 = 5 [round-off to larger direction value ]
So, it would cost = 5 * 3.19 = $15.95
In short, Sam's club offers the better deal.
Now, we can spend our minimum expense, by buying 3 pcs. of bun from Sam's club and 2 from walmart.
In that case, it would cost = 3*3.19 + 2*2.99 = $15.55
Hope this helps!

Answer: Mike started with 75 cards
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The number of cards mike started with (x) plus the new cards added (7) must be divided by 2 (since his dog ate half of his collection).
That expression must be equal to the number of cards left (41)
Mathematically speaking:
(x + 7) /2 = 41
Solving for x:
x+7 = 41x2
x+7 = 82
x = 82-7
x = 75 cards
Feel free to ask for more if needed or if you did not understand something.
