Answer:
$480
Explanation:
For every tree, she earns $1
multiply tree cost, per trees done in one (1) hour
1 * 10 = 10
Kiera earns $10 every hour
multiply the hourly rate, per hours (worked) per day
10 * 3 = 30
$30 per day
multiply days worked, by the amount (of $) per day
30 * 16 = 480
$480 for 16 days of work
hope this helps:)
