KFC sells whole chicken dinners for 12 and half chicken dinners for 8. Yesterday it sold a total of 400 dinners and took in 4200. How many of each size dinner were sold? What were the cedi sales of each size dinner?​

150 half chicken and 250 full chicken

Step-by-step explanation:

Represent whole chicken with w and half chicken with h.

So, we have:

Which implies that:

Also:

Which implies that:

So, we are to solve for h and w from:

Make h the subject in the first equation

Substitute 400 - w for h in the second equation

Recall that:

y - y1 = m(x- x1)

y - (-5) = 2/3(x -0)

y + 5 = 2/3x

y = 2/3x - 5

5x+10 is the correct one

hope this
