Which problem can best be solved with the inequality 40 – 3x ≥ 5?

The problem "You bring $40 to the carnival. You need to keep at least $5 for the bus ride home. How many $3 rides can you go on?" can be solved using the given inequality.

Solution:

The given inequality is

For the best solution of the inequality, we need to subtract 40 from both the side of the equation for getting the value of x.  

Now subtracting 40 from both side we get,

Now if we put the value of x in the equation, we get,  

The value of

The answer for the problem will be maximum of 11 rides can be taken.

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
