A shop sells orange juice in the following ways: 250 ml bottle for £0.75
1.25 litre carton for £2.30 each or 2 cartons for £3
2 litre carton for £3.75

What's the cheapest way of buying exactly 3 litres with no extra?
Find the amount of each type of bottle or carton you need and the total cost of buying 3 litres

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
