We want to calculate what is the relationship between the amount Diego collected and the amount Carlos collected. To do so we will calculate the ratio of Diego's quantities and CArlos' quantities.
For example, note that for the first month we have
[tex]\frac{28}{7}=4[/tex]
for the second month, we have
[tex]\frac{56}{14}=4[/tex]
for the third month we have
[tex]\frac{84}{21}=4[/tex]
We can check that for each month we have that the quantity Diego collected divided by the quantity Carlos collected would give a ratio of 4.
This means that Diego collected always 4 times more than Carlos
