B. At a supermarket, broccoli and celery are sold at $0.59 per 100 g and$0.26 per 100 g respectively. How much do 1.2 kg of broccoli and 950 g ofcelery cost altogether?
Answers
Step-by-step explanation:
1000g = 1kg
100g of broccoli = 0.59
1.2kg(1200g) of broccoli = 0.59/100 × 1200
= $ 7.08
100g of celery = 0.26
950g of celery = 0.26/100 x 950
= $ 2.47
Total Cost = 7.08 + 2.47 = $ 9.55
Given: Cost of 100g broccoli = $0.59
Cost of 100g celery = $0.26
To find: Cost of 1.2 kg broccoli and 950 g celery altogether
Solution: According to the given question,
Cost of 100g broccoli = $0.59
Using unitary method:
Cost of 1 g broccoli = 0.59/100
now, 1.2 kg = 1,200 g
Cost of 1200 g broccoli = cost of 1 g broccoli x 1200
= 0.59/100 x 1200
= $ 7.08
Cost of 100g celery = $0.26
Using unitary method:
Cost of 1 g celery = 0.26/100
Cost of 950 g celery = cost of 1 g celery x 950
= 0.26/100 x 950
= $ 2.47
Total cost of 1.2 kg broccoli and 950 g celery = Cost of 1200g broccoli + cost of 950g celery
= $ 7.08 + $ 2.47 = $ 9.55
Therefore, 1.2 kg of broccoli and 950 g of celery altogether cost $9.55.
