Each crate holds 25 reusable water bottles. Each crate costs $45. How much should the track team charge for each water bottle to

Reptile [31]

Answer:

$ 9 each bottle

Step-by-step explanation:

1 crate = $45

1 crate = 25 bottles

if we want to earn $180 per crate , we have to add this value to the $45

45 + 180 = 225

if the value of the box to win $180 is $225, we have to divide the new value by 25 (number of bottles) and we will have what we will have to charge each bottle

225/25 = 9

we have to charge $ 9 each bottle to earn $ 180 per crate
