John buys 8 packs of cookies at the grocery store. the cookies are on sale for 50 cent off per pack. he spends $20. which equation can be used to find the original cost of a box of cookies, c?
Let the original cost of a box of cookies be "c".
Since John buys 8 packs of cookies and each pack is 50 cents off, the amount he saves per pack is 50 cents.
So, the total amount he saves is 50 cents/pack * 8 packs = 400 cents.
If the original cost of a box of cookies is "c", then the cost of 8 packs of cookies would be 8 * c cents.
But John spends $20, which is equal to 2000 cents.
Therefore, the equation to find the original cost of a box of cookies, c, can be written as:
8c = 2000 - 400
8c = 1600
Dividing both sides by 8, we get:
c = 200
Hence, the original cost of a box of cookies, c, is $2.
To find the original cost of a box of cookies, c, given that John bought 8 packs of cookies on sale for 50 cents off each pack and spent $20, we can use the following equation:
Original cost of the box of cookies = (Number of packs * Cost per pack) + Discount
In this case, the number of packs is 8, and the discount is 50 cents off per pack. The original cost per pack would then be the cost per pack minus the discount, which is the same as the cost per pack minus 50 cents.
So the equation becomes:
c = (8 * (Cost per pack - 50 cents)) + $20
Therefore, the equation that can be used to find the original cost of a box of cookies, c, is:
c = (8 * (Cost per pack - 0.50)) + 20
John buys 8 packs of cookies at the grocery store. the cookies are on sale for 50 cent off per pack. he spends $20. which equation can be used to find the original cost of a box of cookies, c?
8(c + 0.50) = 20
8c - 0.50 =20
8(c-0.50)=20
8-0.50c = 20
The correct equation that can be used to find the original cost of a box of cookies, c, is:
8(c - 0.50) = 20
This equation takes into account the fact that John bought 8 packs of cookies on sale for 50 cents off each pack. By subtracting 0.50 from the cost per pack, we get the original cost per pack. Multiplying this original cost per pack by 8 gives us the total cost of 8 packs of cookies. Setting this equal to $20 allows us to solve for the original cost of a box of cookies, c.
consider this equation:
4(3x - 2)=-24
Part 1. what is your first step in solving this equation? Remember there is more than one way to solve this equation
Part 2. How would you isolate the variable and solve for x after you have completed part 1
You don't need to solve the problem. Simply describe your process: please label Part 1 and Part 2 in your answer 3 to 5 sentences
Part 1: The first step in solving the equation 4(3x - 2) = -24 is to distribute the 4 to the terms inside the parentheses. This can be done by multiplying 4 with both 3x and -2.
Part 2: After distributing the 4, we get 12x - 8 = -24. To isolate the variable x, we can start by adding 8 to both sides to get rid of the -8 term. This gives us 12x = -16. Then, we divide both sides by 12 to solve for x. Finally, we simplify the equation by dividing -16 by 12, so the final solution is x = -4/3 or -1.33.
