Question

If 5 ibs apples cost $2.99, how much would 3 ibs cost?

Answer 1

We know that 5 lbs of apples cost $2.99

To know how much do 3 lbs of apple cost, you can use cross multiplication

If 5 lbs cost $2.99

Then 3 lbs cost $x

The proportion between the price and the number of apples is the same, you have to calculate it as:

`\begin{gathered} (2.99)/(5)=(x)/(3) \\ ((2.99)/(5))\cdot3=x \\ x=1.794 \end{gathered}`

3 lbs of apples cost $1.79
