Answer:
Let n be the number of 25 cent stamps.Then, 28 - n must be the number of 29 cent stamps.Tim paid $7.60 the stamps.
 0.25n + 0.29(28 - n) = 7.60
 This means that n stamps at 25 cents a piece plus (28 - n) stamps at 29 cents a piece sum to $7.60.Solve for m.
 0.25n + 8.12 - 0.29n = 7.60
 -0.04n = -0.52
 n = 13
 So, Tim bought 13 25-cent stamps and 28 - 13 = 15 29-cent stamps

If the first gardener can finish the job in 6 hours, it means that every hour he completes 1/6 of the job.
By the same logic, the second gardener completes 1/7 of the job per hour.
So, if they work together, they complete

of the job per hour.
So, after 42/13 of a hour, they'll complete the job. Since one hour is made of 60 minutes, 42/13 of a hour is

So, it will take them about 194 minutes to finish the job, i.e. about 3 hours and 14 minutes.
 
        
             
        
        
        
Hey there!☺
 (-∞, 5)

You need to convert the inequality as an interval notation.
 as interval notation would be written like this:
