ryan budgets $35 a week for lunch for 5 days. what is his average lunch expense each day?

Question

i just want to understand this pleaseee

Answer 1

When you're finding the average of something, you divide what you're averaging by what you're averaging it over. "per" and "each" are common keywords separating the two.

 

In this case, you want the average expense each day, so you divide your total expense by the number of days.

 

$35 / 5 days = $7 / day or 7 dollars per day
