Answer:
<h2><u>
15.12 is the discount</u></h2><h2><u>
68.88 is the sell price</u></h2>
Step-by-step explanation:
When you are taking off percentages from numbers, you first want to make the percent a number. This step is super simple. Just divide the 18 by 100
This gets you 0.18
Now multiply
84 * 0.18 = 15.12
So 15.12 is the discount
Then take 84 and subtract 15.12
84 - 15.12 = 68.88
So 68.88 is the sell price
What are you trying to prove here? I know when step will be the use of the Transitive Property. If a=b, and b=c, then a=c.
Step 1: Let's review the information provided to us to answer the problem correctly:
• Option 1: $5.99 for 12 coffees
,
• Option 2: $ 23.99 for 70 coffee
Step 2: Let's calculate the cost of a coffee in each option, as follows:
• Cost of a coffee in Option 1 = 5.99/12 = 0.50 (rounding to the next cent): This means that every cup of coffee costs $ 0.50
• Cost of a coffe in Option 2 = 23.99/70 = 0.34 This means that every cup of coffee costs $ 0.34
Step 3: Now we can decide which is the better deal and why.
The better deal is option ........ because it is cheaper than option..........
You can complete step 3, Kay.
10,060 would be the answer.
Let's use the equation 5x - 20 = 10 as an example for this.
To work backwards from this, you would add the same amount to each side.
You want to isolate the 5x so that you can solve for x.
To do that, you would add 20.
But again, you must add and subtract the same amount to both sides.
So it would look a bit like this:
5x - 20 + 20 = 10 + 20
That would simplify to 5x = 30, or in other words, x = 6.
Basically, you isolate the multiple of the variable then divide the answer to the equation from that multiple.
In the example, 5 is the multiple and after isolating it, the answer was 30.
30 ÷ 5 = 6
x = 6
Hope this helps :)
