Answer 2

To find : cost of $1$ cake , $3$ cakes and $9$ cakes .

Given : cost of $2$ cakes = $ $5$

Solution :

• We know that cost of $2$ cakes = $ $5$

        then cost of  $1$ cake = $ $(\frac{5}{2} )$

                                         = $ $2.5$

• Now , we can find cost of two cakes ,

           cost of $2$ cakes = $$2.5\times 2$

                                     = $ $5$

• Similarly, cost of three cakes is ,

         cost of $3$ cakes = $ $2.5 \times 3$

                                   = $ $7.5$

Hence , cost of $1$ cake , $3$ cakes and $9$ cakes is $2.5 , 5, 7.5$ respectively .
