Answer 2

Let's find the price( Cost Price) he paid for the eggs
\[CP=\frac{a}{12} \times r\]
Do you get this?

Answer 3

okay..

Answer 4

He sold a eggs for s cents each, so selling price (SP)
\[SP= a\times s\]
Profit in cents=
\[\text{Profit in Cents}=SP-CP=a\times s-\frac{a}{12}\times r\]

Answer 5

can u simplify that?

Answer 6

\[\text{Profit in Cents}=a\times s-\frac{a}{12}\times r=a \times (s-\frac{r}{12})\]

Answer 7

\[\frac{a(12s-r)}{12}\---> this is the answer, how do we get this?

Answer 8

\[\frac{a(12s-r)}{12}\]
this one

Answer 9

\[\text{Profit in Cents}=a\times s-\frac{a}{12}\times r=a \times (s-\frac{r}{12})=a(\frac{s\times 12}{1\times 12}-\frac{r}{12})\]\[=a(\frac{12s-r}{12})\]

Answer 10

Do you understand this?

Answer 11
