Question

Can anyone help me please and explain this: Write "60 pounds for $6.60" as a unit rate per ounce to the nearest tenth. 1 pound= 16 ounces
A: 1 lb/176 cents
B: 3 lb/ 33 cents
C: 1 lb/ 3.8 cents
D: 1 lb/ 0.7 cents

Answer 1

If the rate is 60 pounds for $6.60 and we need to convert it to a unit rate per ounce, you will think of it as $6.60 for 60 pounds instead.

Divide to get a unit rate per pound.

$0.11 per pound

To convert this to an amount per ounce Change the rate to say $0.11 per 16 ounces(this means the same).

Divide 0.11 by 16 to get 0.006875 or $0.007 or 0.7 cents per ounce. Choice D but it should say per ounce, not per pound.
