Second part
Answer: She requires 5.44 gallons
Step-by-step explanation:
From the previous calculations,
area of deck that needs to be sealed = 1849 square ft
1 coat means the paint would be applied once. Let x represent the number of gallons of sealer needed to seal the deck.
From the information given,
1 gallon of sealer = 340 square feet
x gallons of sealer = 1849 square feet
By cross multiplying,
340 * x = 1 * 1849
340x = 1849
x = 1849/340
x = 5.44
She requires 5.44 gallons
