Answer:
The inequality that represents the situation is 20x ≥ 3000
The least number of Bengal Cards that the team must sell is 150.
Step-by-step explanation:
If we call x the number of Bengal Cards that the team will sell, the amount that the team will raise can be calculated as $20 times x or:
20x
Then, this quantity should be at least $3000, so we can write an inequality as:
20x ≥ 3000
Finally, to find the least number of Bengal Cards, we need to divide both sides by 20 as:
20x/20 ≥ 3000/20
x ≥ 150
Therefore, the inequality that represents the situation is 20x ≥ 3000 and the least number of Bengal Cards that the team must sell is 150.
