Question

The table below shows the number of grapes and cups of water used to make fruit punch according to a certain recipe. Grapes 52 and 39 water cups 16 and 12 How many cups of water are needed for every 1 grape?

Answer 1

To find the number of cups of water needed for every 1 grape, divide the difference between the 2 values of cups of water by the difference between the 2 values of grapes, just as if you were finding a slope:

`m=(16-12)/(52-39)=(4)/(13)=0.31`

It means that 0.31 cups of water are needed for every grape.
