Question 210396
To find the number of grams per penny, just divide the number of grams by the number of pennies.
For the large tin:
{{{794/28.5 = highlight(27.8596)}}}grams per penny.
For the small tin:
{{{142/7 = highlight(20.2857)}}}grams per penny.
The difference in price is:
{{{27.8596-20.2857 = 7.5739}}}grams per penny.
The cost of the large tin is less, per penny, than the cost of the small tin by 27.19%.
{{{(7.5739/27.8596) = 27.19}}}%
