Question

it costs 4.25 for 1 pound of roast beef. how much will it cost to purchase 2.5 pounds of roast beef? round to nearest cent

Answer 1

Answer:

$10.64

Step-by-step explanation:

We know that 1 pound, costs $4.25, so to begin I added that together. And gave myself 8.50. Now, we know that we have 2 pounds. We need 2.5 so, I devided 425 by 2, and got 213.5. Now I know I have to round to the nearest cent. And 213.5 would round to 214. Now we put the decimal back in place and add our 2.14 to our 8.50 and get $10.64
