Raymond is buying boxes for his sons birthday party. he has to decide on how many boxes he should purchase. 25 children are attending the birthday party. if one child gets 3 favors and there are 15 favors in each box. how many boxes should he buy.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

both equations and proportions are better.
