Answer:

$\frac{7}{9}$

Step-by-step explanation:

Given

0.77......

We require 2 equations with the repeating part after the decimal point.

let x = 0.77.... (1) ← multiply both sides by 10

10x = 7.77.... (2)

Subtract (1) from (2) thus eliminating the repeating decimal

9x = 7 ( divide both sides by 9 )

x = $\frac{7}{9}$

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
