121.836

Step-by-step explanation: So the first thing you need to do is:

31.24        

x3.90           you need to put the zero there because the decimal points would need to match up.

Once you do that just put the decimal down. Like this:

31.24        

x3.90

          Once you do that just ignore the decimal and multiply.

   .

Once you have finished, the answer should be 121.836.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
