You want to make some apple pies. Apples cost $1.40 per pound. How much does it cost to buy 16.2 pounds of apples?

Answer 1

#$22.68#

It costs #$1.40# for #1# pound. You wish to know the cost of #16.2# pounds.

That means the price must be raised #16.2# times.

#($1.40)/"1 lb" xx "16.2 lb" = $22.68#

Remember #$1.40 xx 1# pound will give you the same amount, thus the more the amount of pounds increases, so too must the price increase at that rate.

To find out how much it costs to buy 16.2 pounds of apples at $1.40 per pound, you multiply the weight of the apples by the cost per pound:

[ \text{Cost} = \text{Weight} \times \text{Cost per pound} ]

[ \text{Cost} = 16.2 \text{ pounds} \times $1.40/\text{pound} ]
