Esmerelda rents a car from a company that rents cars by the hour. She has to pay an initial fee of $50, and then they charge her
Semenov [28]
Alright so I'm gonna set up an inequality for this. Let x be the hours

50 + 9x ≤ 200
9x ≤ 150
x ≤ 16.6

They said that the car cannot be rented for part of an hour so that means we must found it down. the max she can rent it for is 16 hours.

Check: 9*16 + 50 = 194 which is just under her budget

A bicyclist travels at a constant speed of 12 miles per hour for a total of 45 minutes. (Use set notation for the domain and ran
Mamont248 [21]

A bicyclist travels at a constant speed of 12 miles per hour for a total of 45 minutes.

We know the formula , Distance = speed * time

Speed is constant and it is 12. So it  is linear

The function becomes d = 12t, x is the t is the time and d is the distance

At the starting point, t=0  and distance d=0

End point , t=45 min = 0.75 hours and distance = 12 * 0.75 = 9

So domain (t) is {x|0}

Range (d) is {y|0}

matrenka [14]
She'll need 13 boxes! 10 divided by 127 is 12 and there's  a remainder of 7. so seven crayons will fill the 13th box :)
