Complete question is;

It took Priya 5 minutes to fill a cooler with 8 gallons of water from a faucet that was flowing at a steady rate. Let w be the number of gallons of water in the cooler after t minutes. Which of the following equations represent the relationship between w and t? Select all that apply

A) w = 1.6t

B) w = 0.625t

C) t = 1.6w

D) t = 0.625w

Option A: w = 1.6t

& Option D: t = 0.625w

Step-by-step explanation:

We are told It took Priya 5 minutes to fill a cooler with 8 gallons of water at a steady rate.

Thus;

Rate of filling = 8 gallons/5 minutes = 1.6 gallons/minutes

Now, we are told that w is the number of gallons of water in the cooler after t minutes.

Thus, to find w, we will multiply the rate by t minutes.

w = 1.6 gallons/minutes × t minutes

w = 1.6t gallons

Or we can write as;

w/1.6 = t gallons

0.625w = t gallons

Therefore, options A & D are correct.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
