Answer:
1) $283.50
2) 65.21 meters.
Step-by-step explanation:
Part 1)
We know that a spool of ribbon holds 6.75 meters.
A craft club buys 21 spools.
So, the total length of ribbon bought is:

Each meter costs $2. So, the total cost will be:

Part 2)
A spool holds 6.75 meters.
We bought 21 of them, so that total length we have is 141.75 meters.
The club used 76.54 meters.
So, the amount of ribbon that is left is represented by:

Subtract:

So, 65.21 meters of ribbon will be left.
Answer:
Step-by-step explanation:
Let p represent the number of calories in a peach and g the number of calories in an orange.
Then p = g + w.
From this we get g = p - w.
In words: "The number of calories we get from an orange is equal to p, the number of calories from a peach, less w calories."
There would be a 15% chance of not experiencing both side effects.
Hope this helps!
