Answer:
3+x≥-16
Step-by-step explanation:
The least number of each pack that Martin can buy is 5 packs of burger and 3 packs of bread buns.
Since the packs of bread buns contain 40 <em>bread buns </em>and each pack of burgers contains <em>24 burgers,</em> then we'll calculate the multiples of each number. This will be:
Multiples of 24 = 24, 48, 72, 96, 120
Multiples of 40 = 40, 80, 120, ...
Therefore, the least common multiple is 120.
The least number of packs of burger to buy is 5 and least number of packs of bread buns to buy is 3.
