i am pretty sure about that
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.
w is the width and it is the independent variable. You can pick any positive whole number you want (within reason of course; you can't go to infinity or go beyond some set boundary). Whatever you picked for w, the expression 2w-5 will be dependent on it. So the length is dependent on the width.
For instance, if the width is w = 10 feet, then 2w-5 = 2*10-5 = 20-5 = 15 feet is the length. The choice of 10 feet for the width directly affects the length being 15 feet.
