Acertain vegetable recipe requires 5 brussels sprouts per person. melvin has a dozen brussels sprouts. write an equation to find out how many more does he need to prepare the vegetable dish for 9 guests and solve.

To find out how many more brussel spouts Melvin needs, you will subtract the total amount needed and the amount he has.

To find how many he needs you multiply 9 x 5 = 45 brussel sprouts.

If he has a dozen (12), Melvin will still need 33 brussel sprouts (45 - 12).

The equation showing this is:

(5 x 9) - 12 = b, where b is the number of brussel sprouts needed.
