Question

If four pounds of potatoes cost $6.00, how much would 10 pounds of potatoes cost. 

Answer 1

Hi Alyssa,

You can solve this problem using a unit rate. Let's find the cost of 1 pound of potatoes using the information that 4 pounds cost $6:

$6 = x

4 pounds 1 pound

$6 ÷ 4 = x

4 pounds 4 1 pound

x = $1.50 for 1 pound

Then for 10 pounds, multiply this cost for 1 pound by 10:

$1.50 x 10 = $15.00 for 10 pounds
