Kobotan [32]

Answer:

Sampson gains 3.967 kilograms from November to February.

Step-by-step explanation:

Given:

Actual Weight on November 15 = 2.49 kg

On December 15, he weighed 1020 grams more

Since 1000 grams = 1 kg

Weight on December 15 = 1020 grams = 1.2 kg

Hence Weight gained from November 15 to December 15 = 1.2 kg

On January 15, he had gained another 2200 grams

Weight on January 15 = 2200 grams = 2.2 kg

Hence Weight gained from December 15 to January 15 = 2.2 kg

On February 15, he had only gained 0.567 kilograms.

Weight on February 15 = 0.567 kg

Hence Weight gained from January 15 to February 15 = 2.2 kg

Total weight gained from November to February = Weight gained from November 15 to December 15 + Weight gained from December 15 to January 15 + Weight gained from January 15 to February 15

Total weight gained from November to February = $1.2+2.2+0.567 = 3.967 \ kg$

Hence Sampson gained total weight of 3.967 kg from November to February.

The percentage here must be assumed as by volume. Therefore, it means that the solution has 0.18 gallons of detergent / gallon of solution. If Meryl needs to add 11 gallons of water then she has 2.41 gallons of detergent. Calculation is as follows:

.18 = x / x+4

Solving for x, we obtain

x = 2.41
