Question

At a grocery store, an uncooked beef roast is on sale for $4.99/lb , at the same grocery store prepared roast beef is available for $2.99/100g, how many times more expensive is the deli roast compared to the uncooked roast

Answer 1

453,59 grams equals 1 lb
Uncooked beef rost is $4.99/ 453,59 grams
That is $1.10 /100grams

The cooked one costs $2.99/100grams

That means that the deli beef roast is 2.71 times more expensive that the uncooked one ( per 100 grams)

2.99/1.10=2.71
