Answer:
8 pounds of cheaper candy,
17.5 pounds of expensive candy
Step-by-step explanation:
Let's define some variables. Let's say the amount of pounds of candy that sells for $2.20/lb is x, and the $7.30 is y. Now we can write some equations!
x + y = 25.5
We can start substitution. We can say that x = 25.5 - y. Plugging this into our second equation, we get:
y = 17.5
Plugging this in, we find that:
x = 8.
This means that...
the first worker does 1/8 of the job each hour.
the second worker does 1/4 of the job each hour.
the third worker does 1/4 of the job each hour.
So together they get 1/8+1/4+1/4 of the job done per hour.
Rate: 5/8 of the job per hour
Now if we know the rate, the job will be finished in...
1/(5/8) hours ----> 1.6 hours or 1 hour and 36 minutes
answer: 1.6 hours or 1 hour and 36 minutes
4/25 is already simplified
ASA because when you look at the corners it marks the angles and then a line for the side in between it. That’s how I always looked at it
