Answer:
Clydesdale drinks a total of 840 gallons in 28 days
Explanation:
Step 1: Calculate rate at which water is drank
The expression for the total amount of water drank is;
Total amount of water=quantity drank per day×number of days
where;
quantity drank per day=g
number of days=4 days
total amount of water drank=120 gallons
replacing;
120=(g×4)
4 g=120
g=120/4
g=30
Quantity drank per day=30 gallons per day
Step 2: Total amount he drinks in 28 days
Using the expression;
Total amount of water=quantity drank per day×number of days
where;
quantity drank per day=30 gallons per day
number of days=28 days
replacing;
Total amount of water=(30×28)=840 gallons
Clydesdale drinks a total of 840 gallons in 28 days
