고, (e) A shop sells bags of compost in three different sizes. Small Medium Large 30 litres $5.82 50 litres $9.45 75 litres $14.50 Work out which size of bag gives the best value. Show how you decide.

The small bag gives the best value.

Step-by-step explanation:

Simply divide the liters by the price to get the liters per price of each bag.

Example:

30/5.82= 8.59...

This has the highest number of the three of them, meaning you get more compost per dollar you spend. Therefore, the small bag is the best value.

Step-by-step explanation:

Find unit rate for each size bag.

Unit rate for small bag = 5.82 ÷ 30  = $ 0.194

Unit rate for medium bag = 9.45 ÷ 50 = $ 0.189

Unit rate for large bag = 14.50 ÷ 75  = $0.193

Medium bag gives the best value as it has lowest unit rate
