Since 12 cost $27, you can use compatible numbers to make it ~$28. So, then for 6, it would cost $14 because you just halve everything. Is that what you are getting at?
4 to the power 4 is 256......
Answer:
The inequality to represent the situation is
and the team must sell at least
"Jaguar Cards".
Step-by-step explanation:
Given: The ADMHS football team is trying to raise money to buy new equipment so the players are selling "Jaguar Cards" for
each.
If the football team needs to raise at least
for equipment.
To find: The inequality to represent the situation and the least number of "Jaguar Cards" the team must sell.
Solution:
Let the ADMHS football team sold
"Jaguar Cards" for
each.
Now, the football team needs to raise at least
for equipment.
So, the inequality to represent the situation is
.
Now, on solving we get,


Hence, the inequality to represent the situation is
and the team must sell at least
"Jaguar Cards".
