![Air freshener A has a mass of 42 grams when opened and its mass decreases by 4.2 grams each day. Air freshener B has a mass of 42 grams when opened and its mass decreases by 4.2% each day.
a. Write a function \( a \) that determines the mass of air freshener A (in grams) in terms of the number of days \( t \) since it was opened.
\[ a(t) = 42 - 4.2t \]
b. Write a function \( b \) that determines the mass of air freshener B (in grams) in terms of the number of days \( t \) since it was opened.
There is a syntax error for \( b(t) \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8b115c6f-5415-4099-a9ef-0ff8db89cbd8%2F7e7adeb4-5bdd-4a18-9588-7ba5a3f45599%2Ftmsl2a_processed.png&w=3840&q=75)
