1. A 900g tin of chocolate drink powder costs $12.50 and a 1.45kg tin of the
same brand of chocolate drink powder costs $17.90. Which tin gives the
better value for money?

Powder 2

Step-by-step explanation:

Convert to such a way that both quantities are the same:

Powder 1: 1250/9 = 137.7 c

Powder 2: 1790/14.5 = 123.4 c

By doing the above calculation, we have found the cost of 100g , for both powders. Now, compare and find

137.7 > 123.4

But, we're looking for cheapest value, so choose powder 2.

Hope this helps.

The answer is 114.
