Answer:
a)
To work out the cost for 10ml of juice for each bottle, you can first work out the cost for each bottle for 1 ml.
You can do this by making the ml equal to the cost in an equation and then working with it to get the cost for 1 ml.
Bottle A:
150 = 90 = divide each side by 150 so you can make the ml be 1 and then you can get the cost for 1 ml.
1= 1.67
Bottle B:
250=1.25 - divide each side by 250
1=200
Bottle C:
320=1.76 - divide each side by 320
1=181.81
So now you know the cost of each bottle for 1 ml of juice. You can find the cost of 10ml of juice by multiplying each cost for 1ml by 10.
Bottle A: $16.7
Bottle B: $2000
Bottle C: $1818.1
I am not sure if these values are correct though.
b)
Look at the cost of each bottle when they have the same ml. The smallest value is for bottle A so that is the best value because it is cheaper.
