Question

Ariane feeds her kitten kkk grams of food 222 times in the morning and 222 times in the evening. She feeds her dog ddd grams of food 111 time in the morning and 111 time in the evening. Which expressions can we use to describe how many grams of food Ariane feeds her animals per day?

Answer 1

Given:

• Food given to kitten= kkk grams, 222 times in morning and evening each
• Food given to dog= ddd grams, 111 times in morning and evening each

To find:

Expression for total food consumed by both pets per day

Solution:

Total food consumed by kitten in one day

= 222 x kkk + 222 x kkk

= 444 x kkk

Total food consumed by dog in one day

= 111 x ddd + 111 x ddd

=222 x ddd

Total food consumed= Food consumed by kitten + food consumed by dog

= 444 x kkk + 222 x ddd

= 222 ( 2 x kkk + ddd)

Hence, the total food consumed by both pets in one day can be expressed as 222 ( 2 x kkk + ddd)
