Alright, so here, we can simply divide 0.75/3=0.25 due to that we need to find that we need to find the unit rate of each pound, and we have 3, so we need to divide by 3
Answer:

Step-by-step explanation:
The function that could model this periodic phenomenon will be of the form

The tide varies between 3ft and 9ft, which means its amplitude
is

and its midline
is
.
Furthermore, since at
the tide is at its lowest ( 3 feet ), we know that the trigonometric function we must use is
.
The period of the full cycle is 14 hours, which means


giving us

With all of the values of the variables in place, the function modeling the situation now becomes

Answer:
48,000
Step-by-step explanation:
320,000÷100=3200
1/100=3200
×15=48,000
therefore 15/100=48,000
