For a beach trip, Sarai spends $9 on sunscreen, $18 on beach towels, $22 on food, $9 on a first aid kit, and $11 on sand toys.

Which measure of center will help Sarai determine the average cost of the types of items she brought?
mean
median
mode
outlier

Answer 1

the average cost of the items Sarai brought is $13.80.

Explanation:

$9 + $18 + $22 + $9 + $11 = $69

Since Sarai bought a total of 5 items, we divide the total cost by 5:

$69 ÷ 5 = $13.80
