Answer from: clairajogriggsk

We divide 325 by 48.

The answer comes out to 6.77

But since the number of buses must be a whole number, we will need 7 buses to carry the 325 students and teachers on a field trip.

Answer from: 23basu3

Remember that you can do anything to an equation as long as you do it to both sides so

we find how many buses needed
so basically we need at least 325 people spaces
1 bus=48 people spaces
therefor
how many buses= 48 times number of busses > 325
(> means 'is greater than or equal to')
so 48 times number of busses > 325
divide both sides by 48
number of busses > 325/48
325/48=6 and 37/48
number of busses > 6 and 37/48
the number of busses has to be greater that 6 and 37/48
number of busses also has to be a whole number
(imagine renting a fractional bus, "Ok, so I need 6 and 37/48 busses. No, I don't want 7 busses, that'll cost extra. Yes, I know what I'm doing. What?! You can't? Why?! You people are so incompetent. Of course I don't want to rent 7 busses. Were just going in circles. Have a nice day! *hangs up*")
so therefor we round 6 and 37/48 up to 7 busses
the answe ris 7 busses

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

$y\propto x$

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
