Answer:
The cost of 6 cans of soup = Â $7.8
Step-by-step explanation:
The cost of 10 cans of soup = $13
The number of cans needed for the soup = 6
Now, Cost of 1 can of soup =[tex]\frac{\textrm{Total cost of 10 cans of soup}}{\textrm{10}}[/tex]
= $13 / 10 =$1.3
⇒The cost of 1 can of soup is $1.3
Now, The cost of 6 cans of soup  =  6 x  Cost of 1 can
⇒ 6 x $1.3 =  $7.8
Hence, the cost of 6 cans of soup = Â $7.8
