Answer:
An adolescent snail’s mass is 60% of an adult. The adolescent snail’s mass is 39 grams .The adult mass is equal to 65 grams.
Solution:
Given that adolescent snail’s mass is 60% of an adult.
Let assume mass of an adult = x grams
So adolescent snail’s mass = 60% of x grams
[tex]=\frac{60}{100} \times x[/tex]
adolescent snail’s mass = [tex]\frac{3 x}{5}[/tex] --- eqn 1
From question, it’s given that adolescent snail’s mass is 39 grams.
So we can say eqn1 is equal to 39
[tex]\frac{3 x}{5}=39[/tex]
[tex]3 x=39 \times 5[/tex]
3x=195
x = 65 grams
Hence the adult mass is equal to 65 grams.
