The amount of power why solar panel a can produce with an area of x Square meters can be represented by the equation Y equals 10
vodka [1.7K]

Solar panel B produce more power

Step-by-step explanation:

Given that the amount of power produced by solar panel A with an area of x square meters is modeled by equation y=1020x

For solar panel B, find the equation that models the amount of power produced;

Taking points on the linear graph : (1,1200)  and (2,2400) the slope is given as;

m=Δy/Δx

m=2400-1200/2-1 = 1200/1 =1200

Finding the equation

m=Δy/Δx

y-1200/x-1 =1200

y-1200 = 1200x-1200

y= 1200x

Comparing the two models , when area of solar panel is 2 square meters power produced will be;

Panel A, Y=1020x = 1020*2 = 2040 watts

Panel B, Y=1200x =1200*2 =2400  watts

Hence solar panel B produces more power.

Store B is offering the better deal on ground beef

Step-by-step explanation:

Dean is comparing prices on ground beef

  • Store A is selling 5 pounds of ground beef for $23.49
  • Store B is selling 8 pounds of ground beef for $36.96

We need to know which store is offering the better deal on ground beef

To find the better deal we must to find the unit price of each store

The unit price = total price ÷ number of pounds

∵ Store A is selling 5 pounds of ground beef for $23.49

∴ The unit price of Store A = 23.49 ÷ 5 = $4.698

∴ The unit price of Store A is $4.698 per pound

∵ Store B is selling 8 pounds of ground beef for $36.96

∴ The unit price of Store B = 36.96 ÷ 8 = $4.620

∴ The unit price of Store B is $4.620 per pound

∵ $4.620 < $4.698

∴ The unit price of Store B is less than the unit price of Store B

∴ Store B is cheaper than Store A, then it is offering the better deal

Store B is offering the better deal on ground beef
