A7/2 x 52/3 i hope that correct

Answer 2

Answer: A.
`(7)/(2)*(52)/(3)`

Explanation:

Given: The number of pounds of cat food bought by Gary every 3 weeks. =
`3(1)/(2)\ pound=(7)/(2)\ pound`

If Gary feeds his cat the same amount of food each day.

⇒ The number of pounds of cat food his cat eats each week =
`(7)/(2*3)\ pound`

Since 1 year = 52 weeks

Therefore, the number of pounds of cat food his cat eats each year =
`52*(7)/(2*3)=(7)/(2)*(52)/(3)`

The expression could be used to determine the number of pounds of cat food his cat eats each year is given by :-

`(7)/(2)*(52)/(3)`
