Question

The senior class plans a school trip to Washington DC. Students should bring money for meals and souvenirs. They are told to bring at least $65 but no more then $135.write a compound inequality that represents the amount of money a student can bring.

Answer 1

Answer:

$70

Step-by-step explanation:

it is between both. I hope this helps

Answer 2

Answer:

$65 ≤ x ≤ $135

It can also be written as $65 ≤ x AND x ≤ $135

Step-by-step explanation:

Now, one should know the meaning of compound inequality. A compound inequality is the inequality which simply combines the two simple inequalities.

Now, in an inequality, three relations are performed, equal to, less than and greater than. You can combine 'equal to' with 'less than' or 'greater than' according to situation given.

Notice that in given sign

≤

the value at left side or the pointed side will be small or lesser than the value at right side. Also notify that if inverted, like this ≥

Value of left side will be greater. Means the value at pointed side will always be smaller. The lower bar is sign of equal to

if this is written

x ≤ 3

It means that x can be equal to three or any value less than 3 means 2,1,0,-1 etc.

Now in question given, it is stated that money should be not less than $65 means it can either be $65 or more but not less than it. Lets assume 'x' as the amount required,

So one inequality is

$65 ≤ x

For second condition which is amount should be no more than $135, means it can be $135 or less, so inequality is

x ≤ $135

Remember that we use AND in the answer because both statements of inequality are need to be fulfilled or satisfied.
