FIND the ESTIMATE: 1) A RARE TRUFFLE ONCE SOLD FO $13.20 FOR A 0.44 OZ CAN. APPROXIMATELY HOW MUCH WOULD 1LB OF THIS TRUFFLE COST?
*September 5, 2011*

**MATH**

i am really confused is this how it should be for the actual cost $13.20 divide 0.44 oz = 30 x 16 = $480 for 1 lb for the estimate: $13 divide by 0.40oz = 32.5 x 16 = $520 pls advise
*September 5, 2011*

**MATH**

i thought i would estimate: 13.20 to 13 and .44 oz to .40 1300 divide by 40 is 32.5 per oz so 16oz equal to 1lb 32.5 x 16 : $5.20

Ms: Sue need to find th estimate: a rare truffle once sold for $13.20 for 0.44 oz can approximately how much would 1 lb of this truffle cost? would it be estimate; 13.00 x 0.40 = 32.5 x 16 = 5.20?
