Question

Date:

5.
Apples cost $1.39 per kilogram. If you have $6.00,
can you purchase a 3.75 kg bag of these apples?
Explain how you could make an estimate to be
sure, before you purchase the apples.
Find the cost of the apples.

Answer 1

Yes

Explanation:

We know that 1.39 is less than 1.5 and 3.75 is less than 4.

Hence the price of 3.75kg is going to be less than: 4*1.5=$6

Given that apples cost $1.39 per kilogram, then the price of 3.75 kg of apples is 3.75*1.39=$ 5.2125.

Because 5.2125 is actually less than $6

This means that $6 can buy 3.75 kg of apples.
