Answer:
The larger ham is the better buy.
Step-by-step explanation:
In order to determine the better buy, divide both of the prices by their weight to get the price per pound of ham.
5.70/3 = 1.90 per lb
8.75/5 = 1.75 per lb
Therefore the 5 pound of ham is a better buy.
Answer:
8/17 and 9/17
Step-by-step explanation:
8:9
both add up to 17
so it can be 8/17 or 9 but it cannot be simplified unless if you want them both as a mixed number which is
8/17 as a mixed number is 2 1/17
9/17 as a mixed number is 1 8/17
Answer: $467.21
Step-by-step explanation:
8% of 600 = 48
600 - 48 = 552
8% of 552 = 44.16
552 - 44.16 = 507.84
8% of 507.84 = 40.6272
8% of 507.84 ≈ 40.63
507.84 - 40.63 = 467.21
