Question

Jenna feeds her cat twice a day. She gives her cat 3/4 can of cat food each time. Jenna is having a friend take care of her cat for 5 days. To prepare, she bought 8 cans of cat food. Did Jenna buy enough cat food? If so, how much? If not, how much did she have?

Answer 1

Given:

Number of times Jenna feeds her cat = 2

Cat food each time $=\dfrac{3}{4}\text{ can}$

Number of days = 5

Number of cans she bought = 8

To find:

Did Jenna buy enough cat food.

Solution:

Required food for each time  $=\dfrac{3}{4}\text{ can}$

Jenna feeds her cat twice a day.

Required food for a day $=2\times \dfrac{3}{4}\text{ can}$

                          $=\dfrac{3}{2}\text{ can}$

Required food for 5 days $=5\times \dfrac{3}{2}\text{ can}$

                           $=\dfrac{15}{2}\text{ can}$

                           $=7.5\text{ can}$

Since, 7.5 cans < 8 cans, therefore, Jenna buy enough cat food for her cat.
