Answer:
84 cookies
Step-by-step explanation:
First, find the amount she bakes per minute. It is given that Marissa bakes 30 cookies every 15 minutes, or:
30 cookies/15 minutes = 2 cookies/minute.
Marissa bakes 2 cookies per minute. Multiply 2 with 42 minutes to find the total cookies baked in 42 minutes:
42 x 2 = 84
84 cookies is your answer.
