3 decreased by 250% = - 4.5
Absolute change (actual difference):
- 4.5 - 3 = - 7.5
Mean = ( 22 + 37 + 49 + 15 + 82 ) / 5
= 41

Answer:
5 bags
Step-by-step explanation:
The volume of the tub is the product of its dimensions:
V = (1.8 m)(0.5 m)(0.25 m) = 0.225 m³
There are 1000 L in 1 m³, so this volume in liters is ...
(0.225 m³)(1000 L/m³) = 225 L
At 50 L per bag, the gardener needs ...
(225 L)/(50 L/bag) = 4.5 bags
The gardener probably cannot purchase a partial bag, so must buy more than is needed.
The gardener must buy 5 bags of compost to fill the tub.
Length is 4
Width is 5
