Answer:
<h3>3 pounds for $1.05 is better since it is 35 cents a pound as opposed to 39 cents a pound for the other product.</h3>
Step-by-step explanation:
We need to find the unit rate. This found by dividing the price by the number of bananas so we get the price for 1 pound of bananas.
$1.97/5 = $0.39
$1.05/3 = $0.35
<h3>3 pounds for $1.05 is better since it is 35 cents a pound as opposed to 39 cents a pound for the other product.</h3>
The answer for that would be 20.75
A bc the Y numbers increase by 17 every time X increases by 1
Let the time taken for the first pipe to fill the pool be x hours
time taken for second pipe to fill the pool is (x+7) hours
time taken for both pipes to fill the pull =(x-9) hours
thus fraction of time taken for both will be written as:
1/(x-9)
thus total fraction for pipe 1 and 2 will be
1/x+1/(x+7)=1/(x-9)
solving for x we get:
x=-3 or x=21
but time is positive, then time taken by first pipe is 21 hours
time taken by both pipes will be 21-9=12 hours
