Number of days= 21/8

Step-by-step explanation:

The inequality to represent the given situation is [tex]2\frac{1}{2}+1\frac{1}{3} \le6[/tex]. Therefore, option B is the correct answer.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given that, Joseph runs [tex]2\frac{1}{2}[/tex] miles on Monday. Each day after that, he runs the same [tex]1\frac{1}{3}[/tex] mile route every morning.

Let the number of days be x.

Here, the inequality is

[tex]2\frac{1}{2}+1\frac{1}{3} \le6[/tex]

Therefore, option B is the correct answer.

Answer: $2,000

Step-by-step explanation:

Gas is $3.25 per gallon. If Monica needs 12 gallons, cost would be:

= 12 * 3.25

= $39

If she wants to fill up for less than $35, she will have to earn the difference in points:

= 39 - 35

= $4

One can get $0.10 off for every $50 spent. The number of 10 cents in $4 is:

= 4 / 0.1

= 40

Monica would therefore have to spend:

= 50 * 40

= $2,000
