A grocery store paid $85 for 4 crates of milk. How much was one crate of milk?

$21.25

Step-by-step explanation:

Divide 85 by 4

85/4 = 21.25

The exact answer is 21.25 but just use 21

There are total 10 juice boxes
P(grape) first pick:
2/10=1/5
P(grape) second pick:
1/9
As a result, the probability that, when Jill reaches into the cooler to grab two juice boxes without replacing them, she grabs two that are grape is 1/45. Hope it help!
