Notice the x^-2, this is equal to 1/x^2. Then notice the y^0, any value raised to the zero power is equal to 1, ie n^0=1. So your expression is actually just:
8/x^2, the y value has no effect upon the output. They want you to evaluate, which must means calculate, the value when x=2 so:
8/(2^2)
8/4
2

Answer:
<em><u>1) Sam's Club is better because the price for 10 cans at the village market would be $6.20 versus $4.70 from Sam's Club</u></em>
<em><u>2) 420 people with 210 per hour</u></em>
<em><u>3) It would be more beneficial to buy apples from the Quick Market considering the explanation below.</u></em>
<em><u>4) 396 quarts per hour and a daily rate of 792.</u></em>
Step-by-step explanation:
1) $3.10 x 2 = $6.20
2) 70 x 6 = 420
so, 210 per hour
3) $1.05 divided by 3 is $0.35 per apple at the Quick Market
$2.55 divided by 5 is $0.51 per apple at the Stop and Save.
4) take 330 and divide by 10 to get the amount per hour which is 33 quarts per hour.
330 + 33 + 33 = 396 for 12 hours
396 x 2 = 792 for one day.
