Question

Lizzie bought 0.8 kg of pears at €1.90 per kilogram and 1.4 kg of apples. The total cost €4.46. What was the price per kilogram of the apples?

Answer 1

The the cost of 1 kg apples = € 2.1

Explanation:

The amount of pears bought by Lizzie = 0.8 kg

The amount of apple bought by Lizzie = 1.4 kg

Total amount paid = €4.46

Now, the cost of 1 kg pears = €1.90 per kg

So, the cost of 0.8 kg pears = 0.8 x (1.90) = €1.52

Now, let the cost of 1 kg apples = € m

So, the cost of 1.4 kg apples = 1.4 x ( € m) = 1.4 m

So, the total amount = Cost of Apples + Cost of Pears

⇒ €4.46 = €1.52 + 1.4 m

or, 1.4 m = 4.46 - 1.52 = 2.94

⇒ m = 2.94/1.4 = 2.1

or, m = 2.1

Hence, the the cost of 1 kg apples = € 2.1
