Question

Jaheed is making punch for a party. The recipe calls for 3.5 liters of fruit juice.


Write a formula to help Jaheed determine the number of cartons of juice he needs to
buy to make the punch.
Let's let
n = number of cartons of juice
m = number of liters in each carton

Answer 1

m * n = 3.5

Answer 2

m * n = 3.5

n cartons * m litres/carton = mn litres = 3.5L

so

you need n = 3.5/m cartons

Answer 3

If each carton contained 0.5 liters you would need n = 3.5/0.5 = 7 cartons.
So you should be able to write the formula now giving n in terms of m

If the recipe needed 3.8 liters of juice then you would get n=3.6/0.5=7.2 cartons
which you would have to round to 8 since 7 would not be enough.

The formula is n=3.5/m rounded up to the nearest whole number

Answer 4
