Amy has a pet dog called Stanley who has a good appetite!
Amy buys dog food in 1.5kg bags.
Stanley eats 0.8kg of food each week.
Amy wants to have enough dog food to last for the next 14 weeks.
She already has two 1.5kg bags.
Can you work out the smallest number of bags that she would need to buy.
Answer:
Total amount required for 14 weeks = 14 x 0.8 = 11.20kg
Additional amount required = 11.20 – 2 x 1.5 = 8.2 kg
Number of bags = 8.2/ 1.5 = 5.47
So, the number of bags she would need to buy is 6 bags
