Question

Gary buys a 31/2 pound bag of cat food every 3 weeks.Gary feeds his cat the same amount of food each day.Write a numeric expression and solve to determine the number of pounds of cat food his cat eats each year?(year=52weeks)

Answer 1

Answer:

$52\times \frac{7}{6}$

$60\frac{2}{3}\text{ pounds}$

Step-by-step explanation:

Given,

The total pounds eaten by cat in 3 weeks = $3\frac{1}{2}$= $\frac{7}{2}$

∵ Each day the pounds of eaten is same,

⇒ Total pounds eaten in each week = $\frac{7}{6}$

∵ 1 year = 52 weeks,

So, the pounds eaten in 52 weeks or 1 year = 52 × pounds eaten in each week

= 52 × $\frac{7}{6}$

Which is the required expression,

By solving it,

The number of pounds eaten by cat in a year

$=\frac{364}{6}$

$=60\frac{2}{3}$
